+Installation Instructions for GPGME
+===================================
+
+ Copyright 2001 g10 Code GmbH
+
+ This file is free software; as a special exception the author gives
+ unlimited permission to copy and/or distribute it, with or without
+ modifications, as long as this notice is preserved.
+
+ This file is distributed in the hope that it will be useful, but
+ WITHOUT ANY WARRANTY, to the extent permitted by law; without even the
+ implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
+
+
+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+------------------------------------------------
+
+ * All error output of the gpgsm backend is send to the bit bucket.
+
+ * The signature verification functions are extended. Instead of
+ always returning GPGME_SIG_STATUS_GOOD, the functions new codes for

+------------------------------------------------
+
+ * gpgme_op_encrypt does now fail with GPGME_Invalid_Recipients if
+ some recipients have been invalid, whereas earlier versions
+ succeeded in this case. The plaintext is still encrypted for all valid
+ recipients, so the application might take this error as a hint that
+ the ciphertext is not usable for all requested recipients.
+ Information about invalid recipients is available with gpgme_get_op_info.
+
+ * gpgme_op_verify now allows to pass an uninitialized data object as
+ its plaintext argument to check for normal and cleartext
+ signatures. The plaintext is then returned in the data object.
+
+ * New interfaces gpgme_set_include_certs and gpgme_get_include_certs
+ to set and get the number of certifications to include in S/MIME
+ signed messages.
+
+ * New interfaces gpgme_op_encrypt_sign and gpgme_op_encrypt_sign_start
+ to encrypt and sign a message in a combined operation.
+
+ * New interface gpgme_op_keylist_ext_start to search for multiple patterns.

+
+Noteworthy changes in version 0.3.3 (2002-02-12)
+------------------------------------------------
+
+ * Fix the Makefile in jnlib.
+
+ * Fix the test suite (hopefully). It should clean up all its state
+ with `make check' now.
+
+
+Noteworthy changes in version 0.3.2 (2002-02-10)
+------------------------------------------------
+
+ * Remove erroneous dependency on libgcrypt in jnlib.
+
+
+Noteworthy changes in version 0.3.1 (2002-02-09)
+------------------------------------------------
+
+ * There is a Texinfo manual documenting the API.
+
+ * The gpgme_set_keylist_mode function returns an error, and changed
+ its meaning. It is no longer usable to select between normal and
+ fast mode (newer versions of GnuPG will always be fast), but
+ selects between local keyring, remote keyserver, or both.
+ For this, two new macros are defined, GPGME_KEYLIST_MODE_LOCAL
+ and GPGME_KEYLIST_MODE_EXTERN. To make it possible to modify the
+ current setting, a fucntion gpgme_get_keylist_mode was added to
+ retrieve the current mode.
+
+ * gpgme_wait accepts a new argument STATUS to return the error status
+ of the operation on the context. Its definition is closer to
+ waitpid() now than before.
+
+ * The LENGTH argument to gpgme_data_new_from_filepart changed its
+ type from off_t to the unsigned size_t.
+
+ * The R_HD argument to the GpgmePassphraseCb type changed its type
+ from void* to void**.
+
+ * New interface gpgme_op_trustlist_end() to match
+ gpgme_op_keylist_end().
+
+ * The CryptPlug modules have been renamed to gpgme-openpgp and
+ gpgme-smime, and they are installed in pkglibdir by `make install'.
+
+ * An idle function can be registered with gpgme_register_idle().
+
+ * The GpgSM backend supports key generation with gpgme_op_genkey().
+
+ * Interface changes relative to the 0.3.0 release:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+gpgme_data_new_from_filepart CHANGED: Type of LENGTH is size_t.
+GpgmePassphraseCb CHANGED: Type of R_HD is void **.
+gpgme_wait CHANGED: New argument STATUS.
+gpgme_set_keylist_mode CHANGED: Type of return value is GpgmeError.
+ The function has a new meaning!
+gpgme_get_keylist_mode NEW
+GPGME_KEYLIST_MODE_LOCAL NEW
+GPGME_KEYLIST_MODE_EXTERN NEW
+gpgme_op_trustlist_next NEW
+GpgmeIdleFunc NEW
+gpgme_register_idle NEW
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Noteworthy changes in version 0.3.0 (2001-12-19)
+------------------------------------------------
+
+ * New interface gpgme_set_protocol() to set the protocol and thus the
+ crypto engine to be used by the context. Currently, the OpenPGP
+ and the CMS protocols are supported. They are specified by the new
+ preprocessor symbols GPGME_PROTOCOL_OpenPGP and GPGME_PROTOCOL_CMS.
+ A new context uses the OpenPGP engine by default.
+
+ * gpgme_get_engine_info() returns information for all crypto engines
+ compiled into the library. The XML format has changed. To
+ reliably get the version of a crypto engine, the <version> tag
+ after the appropriate <protocol> tag has to be looked for.
+
+ * New interface gpgme_engine_check_version(), obsoleting
+ gpgme_check_engine(). Check the version of all engines you are
+ supporting in your software.
+
+ * GpgmeKey lists the user ids in the order as they are returned by
+ GnuPG, first the primary key with index 0, then the sub-user ids.
+
+ * New operation gpgme_op_decrypt_verify() to decrypt and verify
+ signatures simultaneously.
+
+ * The new interface gpgme_op_keylist_end() terminates a pending
+ keylist operation. A keylist operation is also terminated when
+ gpgme_op_keylist_next() returns GPGME_EOF.
+
+ * GPGME can be compiled without GnuPG being installed (`--with-gpg=PATH'),
+ cross-compiled, or even compiled without support for GnuPG
+ (`--without-gpg').
+
+ * GPGME can be compiled with support for GpgSM (GnuPG for S/MIME,
+ `--with-gpgsm=PATH'). It is enabled by default if the `gpgsm' is found
+ in the path, but it can also be compiled without support for GpgSM
+ (`--without-gpgsm').
+
+ * CryptPlug modules for GPGME are included and can be enabled at
+ configure time (`--enable-gpgmeplug'). There is one module which
+ uses the GnuPG engine (`gpgmeplug') and one module which uses the
+ GpgSM engine (`gpgsmplug').
+
+ * Interface changes relative to the latest 0.2.x release:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+gpgme_key_get_as_xml CHANGED: Sub-user ids reversed in order.
+gpgme_key_get_string_attr CHANGED: User ids reversed in order.
+gpgme_key_get_ulong_attr CHANGED: User ids reversed in order.
+gpgme_get_engine_info CHANGED: New format, extended content.
+gpgme_engine_check_version NEW
+gpgme_decrypt_verify_start NEW
+gpgme_decrypt_verify NEW
+gpgme_op_keylist_next NEW
+gpgme_set_protocol NEW
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+Noteworthy changes in version 0.2.3 (2001-09-17)
+------------------------------------------------
+
+ * New function gpgme_get_op_info which can be used to get the micalg
+ parameter needed for MOSS.
+
+ * New functions gpgme_get_armor and gpgme_get_textmode.
+
+ * The usual bug fixes and some minor functionality improvements.
+
+ * Added a simple encryption component for MS-Windows; however the
+ build procedure might have some problems.
+
+
+Noteworthy changes in version 0.2.2 (2001-06-12)
+------------------------------------------------
+
+ * Implemented a key cache.
+
+ * Fixed a race condition under W32 and some other bug fixes.
+
+
+Noteworthy changes in version 0.2.1 (2001-04-02)
+------------------------------------------------
+
+ * Changed debug output and GPGME_DEBUG variable (gpgme/debug.c)
+
+ * Handle GnuPG's new key capabilities output and support revocation
+ et al. attributes
+
+ * Made the W32 support more robust.

+ GPGME - GnuPG Made Easy
+ ---------------------------
+
+ !!!! THIS IS WORK IN PROGRESS !!!
+
+If you want to hack on it, start with one of the `tests/gpg/t-foo'
+programs.
+
+For support of the OpenPGP protocol (default), you need the latest CVS
+version of GnuPG 1.2, see `http://www.gnupg.org/cvs-access.html'.
+
+You need at least GnuPG 1.2.0.
+
+If configure can't find the `gpg' binary in your path, you can specify
+the location with the --with-gpg=/path/to/gpg argument to configure.
+
+For support of the CMS (Cryptographic Message Syntax) protocol, you
+need the latest CVS version of GpgSM, module name `newpg', at
+`:pserver:anoncvs@cvs.gnupg.org:/cvs/aegypten'.
+
+You need at least GpgSM 0.9.0.
+
+If configure can't find the `gpgsm' binary in your path, you can
+specify the location with the --with-gpgsm=/path/to/gpgsm argument to
+configure.
+
+Before building the CVS version following the generic install
+instructions in `INSTALL', you need to set up the build scripts with
+`./autogen.sh'. To build the W32 version, use `./autogen.sh
+--build-w32'. You also need to enable maintainer mode at configure
+time with `--enable-maintainer-mode', or the documentation will not
+built (because the version.texi won't be generated unless maintainer
+mode is enabled).
+
+Please subscribe to the gnupg-devel@gnupg.org mailing list if you want
+to do serious work.

+Hey Emacs, this is -*- outline -*- mode!
+
+* ABI's to break:
+** string representation of non-secret keys and ATTR_IS_SECRET is NULL,
+ which can not be differentiated from the case that it is not
+ representable.
+
+* Thread support:
+** Build thread modules for static linking (which just suck in the
+ desired symbols the hard way). !!
+
+* New features:
+** notification system
+ We need a simple notification system, probably a a simple callback
+ with a string and some optional arguments. This is for example
+ required to notify an application of a changed smartcard, The
+ application can then do whatever is required. There are other
+ usages too. This notfication system should be independent of any
+ contextes of course.
+** --learn-code support
+ This might be integrated with import. we still need to work out how
+ to learn a card when gpg and gpgsm have support for smartcards.
+
+* Documentation
+** Add note about GPGME clearing out pointer return values.
+** validity/trust
+
+* Engines
+** Optimize the case where a data object has an underlying fd we can pass
+ directly to the engine.
+** Move code common to all engines up from gpg to engine.
+** engine operations can return General Error on unknown protocol
+ (it's an internal error, as select_protocol checks already).
+** When server mode is implemented properly, more care has to be taken to
+ release all resources on error (for example to free assuan_cmd).
+** GnuPG
+*** For pipemode, make sure to release the pipemode callback data object.
+ Note, pipemode will eventually be replaced by an Assuan interface to gpg.
+
+* Operations
+** Passphrase callback should not copy password. !!!
+** Export status handler need much more work. !!!
+** Import should return a useful error when one happened.
+** Genkey should return something more useful than General_Error.
+** Factor out common code in _op_*_start functions.
+** Add ATTR to return the number of subkeys or uids.
+** "When returning a GpgmeKey GPGME_ATTR_COMMENT attribute, characters
+ like ":" are not un-escaped, they are returned as \x3a" Bug
+ reported by Stephane Corthesy.
+
+* Error Values
+** Map ASSUAN/GpgSM ERR error values in a better way than is done now. !!
+** Verify (and document) if Read_Error, Write_Error, Pipe_Error set errno.
+
+* Tests
+** Write a fake gpg-agent so that we can supply known passphrases to
+ gpgsm and setup the configuration files to use the agent. Without
+ this we are testing a currently running gpg-agent which is not a
+ clever idea. !
+** t-data
+*** Test gpgme_data_release_and_get_mem.
+*** Test gpgme_data_rewind for invalid types.
+*** Test gpgme_data_read's readable feature.
+
+* Debug
+** Handle malloc and vasprintf errors. But decide first if they should be
+ ignored (and logged with 255?!), or really be assertions. !
+
+* Build suite
+** Make sure everything is cleaned correctly (esp. test area).
+
+Bugs reported by Stephane Corthesy:
+> BTW, here's another bug: it it not possible to retrieve fingerprints
+> for subkeys
+--> This seems to work now (wk 2002-08-20)
+
+> In GpgmeRecipients, would it be possible to provide a function which
+> would return the validity assigned to a name contained in the
+> GpgmeRecipients instance?
+
+> passphrase callback. If I use the same GpgmeContext as the one which
+> is currently asking for a passphrase, my app crashes: the r_hd in
+> the
+> callback has become invalid; if I use a brand new one, the callback
+> is called recursively, when I ask to enumerate keys.

+ How to install and use the Gpgcom Windows Component
+ ===================================================
+ 2001-07-31
+
+
+Installation should be pretty easy:
+-----------------------------------
+
+ * Get and install the latest GnuPG binary for windows
+ (ftp://ftp.gnupg.org/gcrypt/binary/gnupg-w32-1.0.6.zip)
+
+ * Check that you have an untampered version of this package by
+ comparing an MD5SUM against the one on the webpage or by checking
+ the signature of the package using "gpg --verify". See the
+ webpacge for details.
+
+ * Because you are reading this file, you probably have already
+ unpacked it distribution using a unzip utility :-). You should
+ find these files:
+
+ README - This file
+ gpgcom.exe - The Gpgcom server
+ vbtest.html - A Test webpage
+ vbtest.vbs - A VB script to be used with the cscript utility
+
+ * If you are updating Gpgcom, run the old Gpgcom like this:
+
+ c:\gnupg\gpgcom -UnregServer
+
+ (Replace c:\gnupg with the actually used path)
+
+ * Copy the file gpgcom.exe to a some location. C:\gnupg seems to be
+ a good choice.
+
+ * Register the component using this command:
+
+ c:\gnupg\gpgcom -RegServer
+
+ * Ready
+
+Testing the installation:
+-------------------------
+
+ * Make sure that you have a working GnuPG (gpg.exe) and that at least
+ one key is installed.
+
+ * Edit the vbtest.vbs script and replace "alice" in the line
+
+ gpg.AddRecipient "alice"
+
+ with a keyID or user name you have in your key ring.
+
+ * Run the test script:
+
+ cscript vbtest.vbs
+
+ and you should see a valid MIME message with the encrypted text.
+
+
+Using Gpgcom
+------------
+
+Gpgcom currently support only encryption but will be extended to the
+full range of operations GnuPG provides. The 2 examples should goive
+yopu a hint on how to use it. We suggest that you always set armor to
+true, so that the returned text is a string. If you don't use armor,
+the "ciphertext" property will return an array with the binary
+message.

+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.

+@enumerate 0
+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+written document @dfn{free} in the sense of freedom: to assure everyone
+the effective freedom to copy and redistribute it, with or without
+modifying it, either commercially or noncommercially. Secondarily,
+this License preserves for the author and publisher a way to get
+credit for their work, while not being considered responsible for
+modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work that contains a
+notice placed by the copyright holder saying it can be distributed
+under the terms of this License. The ``Document'', below, refers to any
+such manual or work. Any member of the public is a licensee, and is
+addressed as ``you''.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (For example, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, whose contents can be viewed and edited directly and
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup has been designed to thwart or discourage
+subsequent modification by readers is not Transparent. A copy that is
+not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input format,
+@acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML} designed
+for human modification. Opaque formats include PostScript,
+@acronym{PDF}, proprietary formats that can be read and edited only by
+proprietary word processors, @acronym{SGML} or @acronym{XML} for which
+the @acronym{DTD} and/or processing tools are not generally available,
+and the machine-generated @acronym{HTML} produced by some word
+processors for output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies of the Document numbering more than 100,
+and the Document's license notice requires Cover Texts, you must enclose
+the copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a publicly-accessible computer-network location containing a complete
+Transparent copy of the Document, free of added material, which the
+general network-using public has access to download anonymously at no
+charge using public-standard network protocols. If you use the latter
+option, you must take reasonably prudent steps, when you begin
+distribution of Opaque copies in quantity, to ensure that this
+Transparent copy will remain thus accessible at the stated location
+until at least one year after the last time you distribute an Opaque
+copy (directly or through your agents or retailers) of that edition to
+the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document). You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has less than five).
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section entitled ``History'', and its title, and add to
+it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page. If
+there is no section entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on. These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+In any section entitled ``Acknowledgments'' or ``Dedications'',
+preserve the section's title, and preserve in the section all the
+substance and tone of each of the contributor acknowledgments
+and/or dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles. Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section entitled ``Endorsements''. Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section as ``Endorsements''
+or to conflict in title with any Invariant Section.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections entitled ``History''
+in the various original documents, forming one section entitled
+``History''; likewise combine any sections entitled ``Acknowledgments'',
+and any sections entitled ``Dedications''. You must delete all sections
+entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, does not as a whole count as a Modified Version
+of the Document, provided no compilation copyright is claimed for the
+compilation. Such a compilation is called an ``aggregate'', and this
+License does not apply to the other self-contained works thus compiled
+with the Document, on account of their being thus compiled, if they
+are not themselves derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one quarter
+of the entire aggregate, the Document's Cover Texts may be placed on
+covers that surround only the Document within the aggregate.
+Otherwise they must appear on covers around the whole aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License provided that you also include the
+original English version of this License. In case of a disagreement
+between the translation and the original English version of this
+License, the original English version will prevail.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+@uref{http://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.

+@appendixsubsec ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+@smallexample
+@group
+ Copyright (C) @var{year} @var{your name}.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.1
+ or any later version published by the Free Software Foundation;
+ with the Invariant Sections being @var{list their titles}, with the
+ Front-Cover Texts being @var{list}, and with the Back-Cover Texts being @var{list}.
+ A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+@end group
+@end smallexample
+
+If you have no Invariant Sections, write ``with no Invariant Sections''
+instead of saying which ones are invariant. If you have no
+Front-Cover Texts, write ``no Front-Cover Texts'' instead of
+``Front-Cover Texts being @var{list}''; likewise for Back-Cover Texts.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+@node Introduction
+@chapter Introduction
+
+`GnuPG Made Easy' (@acronym{GPGME}) is a C language library that
+allows to add support for cryptography to a program. It is designed
+to make access to crypto engines like GnuPG or GpgSM easier for
+applications. @acronym{GPGME} provides a high-level crypto API for
+encryption, decryption, signing, signature verification and key
+management.
+
+@acronym{GPGME} uses GnuPG and GpgSM as its backends to support
+OpenPGP and the Cryptographic Message Syntax (CMS).
+
+@menu
+* Getting Started:: Purpose of the manual, and how to use it.
+* Features:: Reasons to install and use @acronym{GPGME}.
+* Overview:: Basic architecture of the @acronym{GPGME} library.

+
+
+@node Getting Started
+@section Getting Started
+
+This library documents the @acronym{GPGME} library programming
+interface. All functions and data types provided by the library are
+explained.
+
+The reader is assumed to possess basic knowledge about cryptography in
+general, and public key cryptography in particular. The underlying
+cryptographic engines that are used by the library are not explained,
+but where necessary, special features or requirements by an engine are
+mentioned as far as they are relevant to @acronym{GPGME} or its users.
+
+This manual can be used in several ways. If read from the beginning
+to the end, it gives a good introduction into the library and how it
+can be used in an application. Forward references are included where
+necessary. Later on, the manual can be used as a reference manual to
+get just the information needed about any particular interface of the
+library. Experienced programmers might want to start looking at the
+examples at the end of the manual, and then only read up those parts
+of the interface which are unclear.
+
+
+@node Features
+@section Features
+
+@acronym{GPGME} has a couple of advantages over other libraries doing
+a similar job, and over implementing support for GnuPG or other crypto
+engines into your application directly.
+
+@table @asis
+@item it's free software
+Anybody can use, modify, and redistribute it under the terms of the GNU
+General Public License (@pxref{Copying}).
+
+@item it's flexible
+@acronym{GPGME} provides transparent support for several cryptographic
+protocols by different engines. Currently, @acronym{GPGME} supports
+the OpenPGP protocol using GnuPG as the backend, and the Cryptographic
+Message Syntax using GpgSM as the backend.
+
+@item it's easy
+@acronym{GPGME} hides the differences between the protocols and
+engines from the programmer behind an easy-to-use interface. This way
+the programmer can focus on the other parts of the program, and still
+integrate strong cryptography in his application. Once support for
+@acronym{GPGME} has been added to a program, it is easy to add support
+for other crypto protocols once @acronym{GPGME} backends provide them.
+@end table
+
+
+@node Overview
+@section Overview
+
+@acronym{GPGME} provides a data abstraction that is used to pass data
+to the crypto engine, and receive returned data from it. Data can be
+read from memory or from files, but it can also be provided by a
+callback function.
+
+The actual cryptographic operations are always set within a context.
+A context provides configuration parameters that define the behaviour
+of all operations performed within it. Only one operation per context
+is allowed at any time, but when one operation is finished, you can
+run the next operation in the same context. There can be more than
+one context, and all can run different operations at the same time.
+
+Furthermore, @acronym{GPGME} has rich key management facilities
+including listing keys, querying their attributes, generating,
+importing, exporting and deleting keys, and acquiring information
+about the trust path.
+
+With some precautions, @acronym{GPGME} can be used in a multi-threaded
+environment, although it is not completely thread safe and thus needs
+the support of the application.
+
+
+@node Preparation
+@chapter Preparation
+
+To use @acronym{GPGME}, you have to perform some changes to your
+sources and the build system. The necessary changes are small and
+explained in the following sections. At the end of this chapter, it
+is described how the library is initialized, and how the requirements
+of the library are verified.
+
+@menu
+* Header:: What header file you need to include.
+* Building the Source:: Compiler options to be used.
+* Using Automake:: Compiler options to be used the easy way.
+* Library Version Check:: Getting and verifying the library version.
+* Multi Threading:: How GPGME can be used in an MT environment.
+@end menu
+
+
+@node Header
+@section Header
+@cindex header file
+@cindex include file
+
+All interfaces (data types and functions) of the library are defined
+in the header file `gpgme.h'. You must include this in all programs
+using the library, either directly or through some other header file,
+like this:
+
+@example
+#include <gpgme.h>
+@end example
+
+The name space of @acronym{GPGME} is @code{gpgme_*} for function
+names, @code{Gpgme*} for data types and @code{GPGME_*} for other
+symbols. Symbols internal to @acronym{GPGME} take the form
+@code{_gpgme_*}.
+
+Because @acronym{GPGME} links to the Assuan library, linking to
+@acronym{GPGME} will also use the @code{assuan_*} and @code{_assuan_*}
+name space indirectly.
+
+
+@node Building the Source
+@section Building the Source
+@cindex compiler options
+@cindex compiler flags
+
+If you want to compile a source file including the `gpgme.h' header
+file, you must make sure that the compiler can find it in the
+directory hierarchy. This is accomplished by adding the path to the
+directory in which the header file is located to the compilers include
+file search path (via the @option{-I} option).
+
+However, the path to the include file is determined at the time the
+source is configured. To solve this problem, gpgme ships with a small
+helper program @command{gpgme-config} that knows about the path to the
+include file and other configuration options. The options that need
+to be added to the compiler invocation at compile time are output by
+the @option{--cflags} option to @command{gpgme-config}. The following
+example shows how it can be used at the command line:
+
+@example
+gcc -c foo.c `gpgme-config --cflags`
+@end example
+
+Adding the output of @samp{gpgme-config --cflags} to the compilers
+command line will ensure that the compiler can find the @acronym{GPGME} header
+file.
+
+A similar problem occurs when linking the program with the library.
+Again, the compiler has to find the library files. For this to work,
+the path to the library files has to be added to the library search
+path (via the @option{-L} option). For this, the option
+@option{--libs} to @command{gpgme-config} can be used. For
+convenience, this option also outputs all other options that are
+required to link the program with @acronym{GPGME} (in particular, the
+@samp{-lgpgme} option). The example shows how to link @file{foo.o}
+with the @acronym{GPGME} library to a program @command{foo}.
+
+@example
+gcc -o foo foo.o `gpgme-config --libs`
+@end example
+
+Of course you can also combine both examples to a single command by
+specifying both options to @command{gpgme-config}:
+
+@example
+gcc -o foo foo.c `gpgme-config --cflags --libs`
+@end example
+
+
+@node Using Automake
+@section Using Automake
+@cindex automake
+@cindex autoconf
+
+It is much easier if you use GNU Automake instead writing your own
+Makefiles. If you do that you don't have to worry about finding and
+invoking the @command{gpgme-config} script at all. @acronym{GPGME}
+provides an extension to Automake that does all the work for you.
+
+@c A simple macro for optional variables.
+@macro ovar{varname}
+@r{[}@var{\varname\}@r{]}
+@end macro
+@defmac AM_PATH_GPGME (@ovar{minimum-version}, @ovar{action-if-found}, @ovar{action-if-not-found})
+Check whether @acronym{GPGME} (at least version @var{minimum-version},
+if given) exists on the host system. If it is found, execute
+@var{action-if-found}, otherwise do @var{action-if-not-found}, if
+given.
+
+Additionally, the function defines @code{GPGME_CFLAGS} to the flags
+needed for compilation of the program to find the @file{gpgme.h}
+header file, and @code{GPGME_LIBS} to the linker flags needed to link
+the program to the @acronym{GPGME} library.
+@end defmac
+
+You can use the defined Autoconf variables like this in your
+@file{Makefile.am}:
+
+@example
+AM_CPPFLAGS = $(GPGME_CFLAGS)
+LDADD = $(GPGME_LIBS)
+@end example
+
+
+@node Library Version Check
+@section Library Version Check
+@cindex version check, of the library
+
+@deftypefun {const char *} gpgme_check_version (@w{const char *@var{required_version}})
+The function @code{gpgme_check_version} has three purposes. It can be
+used to retrieve the version number of the library. In addition it
+can verify that the version number is higher than a certain required
+version number. In either case, the function initializes some
+sub-systems, and for this reason alone it must be invoked early in
+your program, before you make use of the other functions in
+@acronym{GPGME}.
+
+If @var{required_version} is @code{NULL}, the function returns a
+pointer to a statically allocated string containing the version number
+of the library.
+
+If @var{required_version} is not @code{NULL}, it should point to a
+string containing a version number, and the function checks that the
+version of the library is at least as high as the version number
+provided. In this case, the function returns a pointer to a
+statically allocated string containing the version number of the
+library. If @var{REQUIRED_VERSION} is not a valid version number, or
+if the version requirement is not met, the function returns
+@code{NULL}.
+
+If you use a version of a library that is backwards compatible with
+older releases, but contains additional interfaces which your program
+uses, this function provides a run-time check if the necessary
+features are provided by the installed version of the library.
+@end deftypefun
+
+
+@node Multi Threading
+@section Multi Threading
+@cindex thread-safeness
+@cindex multi-threading
+
+The @acronym{GPGME} library is not entirely thread-safe, but it can
+still be used in a multi-threaded environment if some care is taken.
+If the following requirements are met, there should be no race
+conditions to worry about:
+
+@itemize @bullet
+@item
+@acronym{GPGME} supports the thread libraries pthread and GNU Pth.
+The support for this has to be enabled at compile time.
+@acronym{GPGME} will automatically detect the location in which the
+thread libraries are installed and activate the support for them.
+
+Support for other thread libraries is very easy to add. Please
+contact us if you have the need.
+
+@item
+If you link your program dynamically to @acronym{GPGME} and your
+supported thread library, @acronym{GPGME} will automatically detect
+the presence of this library and activate its use. If you link to
+both pthread and GNU Pth, @acronym{GPGME} will use the pthread
+support. This feature requires weak symbol support.
+
+@item
+If you link your program statically to @acronym{GPGME}, there is
+currently no easy way to make sure that @acronym{GPGME} detects the
+presence of the thread library. This will be solved in a future
+version.
+
+@item
+The function @code{gpgme_check_version} must be called before any
+other function in the library, because it initializes the thread
+support subsystem in @acronym{GPGME}. To achieve this in all
+generality, it is necessary to synchronize the call to this function
+with all other calls to functions in the library, using the
+synchronization mechanisms available in your thread library.
+Otherwise, specific compiler or CPU memory cache optimizations could
+lead to the situation where a thread is started and uses
+@acronym{GPGME} before the effects of the initialization are visible
+for this thread. It doesn't even suffice to call
+@code{gpgme_check_version} before creating this other
+thread@footnote{In SMP systems the new thread could be started on
+another CPU before the effects of the initialization are seen by that
+CPU's memory cache. Not doing proper synchronization here leads to
+the same problems the double-checked locking idiom has. You might
+find that if you don't do proper synchronization, it still works in
+most configurations. Don't let this fool you. Someday it might lead
+to subtle bugs when someone tries it on a DEC Alpha or an SMP
+machine.}.
+
+For example, if you are using POSIX threads, each thread that wants to
+call functions in @acronym{GPGME} could call the following function
+before any function in the library:
+
+@example
+#include <pthread.h>
+
+void
+initialize_gpgme (void)
+@{
+ static int gpgme_init;
+ static pthread_mutext_t gpgme_init_lock = PTHREAD_MUTEX_INITIALIZER;
+
+ pthread_mutex_lock (&gpgme_init_lock);
+ if (!gpgme_init)
+ @{
+ gpgme_check_version ();
+ gpgme_init = 1;
+ @}
+ pthread_mutex_unlock (&gpgme_init_lock);
+@}
+@end example
+
+@item
+Any @code{GpgmeData}, @code{GpgmeCtx} and @code{GpgmeRecipients}
+object must only be accessed by one thread at a time. If multiple
+threads want to deal with the same object, the caller has to make sure
+that operations on this object are fully synchronized.
+
+@item
+Only one thread at any time is allowed to call @code{gpgme_wait}. If
+multiple threads call this function, the caller must make sure that
+all invocations are fully synchronized.
+@end itemize
+
+
+@node Protocols and Engines
+@chapter Protocols and Engines
+@cindex protocol
+@cindex engine
+@cindex crypto engine
+@cindex backend
+@cindex crypto backend
+
+@acronym{GPGME} supports several cryptographic protocols, however, it
+does not implement them. Rather it uses backends (also called
+engines) which implement the protocol. @acronym{GPGME} uses
+inter-process communication to pass data back and forth between the
+application and the backend, but the details of the communication
+protocol and invocation of the backends is completely hidden by the
+interface. All complexity is handled by @acronym{GPGME}. Where an
+exchange of information between the application and the backend is
+necessary, @acronym{GPGME} provides the necessary callback function
+hooks and further interfaces.

+@node Error Handling
+@chapter Error Handling
+@cindex error handling
+
+Many functions in @acronym{GPGME} can return an error if they fail.
+For this reason, the application should always catch the error
+condition and take appropriate measures, for example by releasing the
+resources and passing the error up to the caller, or by displaying a
+descriptive message to the user and cancelling the operation.
+
+Some error values do not indicate a system error or an error in the
+operation, but the result of an operation that failed properly. For
+example, if you try to decrypt a tempered message, the decryption will
+fail. Another error value actually means that the end of a data
+buffer or list has been reached. The following descriptions explain
+what each error message means in general. Some error values have
+specific meanings if returned by a specific function. Such cases are
+described in the documentation of those functions.

+
+@table @code
+@item GPGME_EOF
+This value indicates the end of a list, buffer or file.
+
+@item GPGME_No_Error
+This value indicates success. The value of this error is @code{0}.
+
+@item GPGME_General_Error
+This value means that something went wrong, but either there is not
+enough information about the problem to return a more useful error
+value, or there is no separate error value for this type of problem.
+
+@item GPGME_Out_Of_Core
+This value means that an out-of-memory condition occurred.
+
+@item GPGME_Invalid_Value
+This value means that some user provided data was out of range. This
+can also refer to objects. For example, if an empty @code{GpgmeData}
+object was expected, but one containing data was provided, this error
+value is returned.
+
+@item GPGME_Busy
+This value is returned if you try to start a new operation in a
+context that is already busy with some earlier operation which was not
+cancelled or finished yet.
+
+@item GPGME_No_Request
+This value is in some sense the opposite of @code{GPGME_Busy}. There
+is no pending operation, but it is required for the function to
+succeed.
+
+@item GPGME_Exec_Error
+This value means that an error occurred when trying to spawn a child
+process.
+
+@item GPGME_Too_Many_Procs
+This value means that there are too many active backend processes.
+
+@item GPGME_Pipe_Error
+This value means that the creation of a pipe failed.
+

+
+@item GPGME_No_Data
+This value means that a @code{GpgmeData} object which was expected to
+have content was found empty.
+
+@item GPGME_Conflict
+This value means that a conflict of some sort occurred.
+
+@item GPGME_Not_Implemented
+This value indicates that the specific function (or operation) is not
+implemented. This error should never happen. It can only occur if
+you use certain values or configuration options which do not work,
+but for which we think that they should work at some later time.
+
+@item GPGME_Read_Error
+This value means that an I/O read operation failed.
+
+@item GPGME_Write_Error
+This value means that an I/O write operation failed.
+
+@item GPGME_Invalid_Type
+This value means that a user provided object was of a wrong or
+incompatible type. Usually this refers to the type of a
+@code{GpgmeData} object.
+
+@item GPGME_Invalid_Mode
+This value means that a @code{GpgmeData} object has an incorrect mode
+of operation (for example, doesn't support output although it is
+attempted to use it as an output buffer).
+
+@item GPGME_File_Error
+This value means that a file I/O operation failed. The value of
+@var{errno} contains the system error value.
+
+@item GPGME_Decryption_Failed
+This value indicates that a decryption operation was unsuccessful.
+
+@item GPGME_No_Passphrase
+This value means that the user did not provide a passphrase when

+@item GPGME_Canceled
+This value means that the operation was canceled.
+
+@item GPGME_Invalid_Key
+This value means that a key was invalid.
+
+@item GPGME_Invalid_Engine
+This value means that the engine that implements the desired protocol

+
+If @var{copy} is not zero, a private copy of the data is made. If

+@cindex signatures, on a key
+
+The signatures on a key are only available if the key was retrieved
+via a listing operation with the @code{GPGME_KEYLIST_MODE_SIGS} mode
+enabled, because it is expensive to retrieve all signatures of a key.
+
+So, before using the below interfaces to retrieve the signatures on a
+key, you have to make sure that the key was listed with signatures
+enabled. One convenient, but blocking, way to do this is to use the
+function @code{gpgme_get_key}.
+
+@deftp {Data type} GpgmeAttr
+The @code{GpgmeAttr} type is used to specify a key signature
+attribute. The following attributes are defined:

+This is the key ID of the key which was used for the signature. It is
+representable as a string.
+
+@item GPGME_ATTR_ALGO

+representable as a string and as a number. The numbers correspond to
+the @code{enum gcry_pk_algos} values in the gcrypt library.
+
+@item GPGME_ATTR_CREATED
+This is the timestamp at creation time of the signature. It is

+@code{0} otherwise.
+
+@c @item GPGME_ATTR_KEY_EXPIRED

+@deftypefun GpgmeCtx gpgme_wait (@w{GpgmeCtx @var{ctx}}, @w{GpgmeError *@var{status}}, @w{int @var{hang}})
+The function @code{gpgme_wait} continues the pending operation within
+the context @var{ctx}. In particular, it ensures the data exchange
+between @acronym{GPGME} and the crypto backend and watches over the
+run time status of the backend process.
+
+If @var{hang} is true, the function does not return until the
+operation is completed or cancelled. Otherwise the function will not
+block for a long time.
+
+The error status of the finished operation is returned in @var{status}
+if @code{gpgme_wait} does not return @code{NULL}.
+
+The @var{ctx} argument can be @code{NULL}. In that case,
+@code{gpgme_wait} waits for any context to complete its operation.
+
+@code{gpgme_wait} can be used only in conjunction with any context
+that has a pending operation initiated with one of the
+@code{gpgme_op_*_start} functions except @code{gpgme_op_keylist_start}
+and @code{gpgme_op_trustlist_start} (for which you should use the
+corresponding @code{gpgme_op_*_next} functions). If @var{ctx} is
+@code{NULL}, all of such contexts are waited upon and possibly
+returned. Synchronous operations running in parallel, as well as key
+and trust item list operations, do not affect @code{gpgme_wait}.
+
+In a multi-threaded environment, only one thread should ever call
+@code{gpgme_wait} at any time, irregardless if @var{ctx} is specified
+or not. This means that all calls to this function should be fully
+synchronized by locking primitives.

+@subsection Using External Event Loops
+@cindex event loop, external
+
+@acronym{GPGME} hides the complexity of the communication between the
+library and the crypto engine. The price of this convenience is that
+the calling thread can block arbitrary long waiting for the data
+returned by the crypto engine. In single-threaded programs, in
+particular if they are interactive, this is an unwanted side-effect.
+OTOH, if @code{gpgme_wait} is used without the @var{hang} option being
+enabled, it might be called unnecessarily often, wasting CPU time that
+could be used otherwise.
+
+The I/O callback interface described in this section lets the user
+take control over what happens when. @acronym{GPGME} will provide the
+user with the file descriptors that should be monitored, and the
+callback functions that should be invoked when a file descriptor is
+ready for reading or writing. It is then the user's responsibility to
+decide when to check the file descriptors and when to invoke the
+callback functions. Usually this is done in an event loop, that also
+checks for events in other parts of the program. If the callback
+functions are only called when the file descriptors are ready,
+@acronym{GPGME} will never block. This gives the user mroe control
+over the program flow, and allows to perform other tasks when
+@acronym{GPGME} would block otherwise.
+
+By using this advanced mechanism, @acronym{GPGME} can be integrated
+smoothly into GUI toolkits like GTK+ even for single-threaded
+programs.

+@subsubsection I/O Callback Example
+
+To actually use an external event loop, you have to implement the I/O
+callback functions that are used by @acronym{GPGME} to register and
+unregister file descriptors. Furthermore, you have to actually
+monitor these file descriptors for activity and call the appropriate
+I/O callbacks.
+
+The following example illustrates how to do that. The example uses
+locking to show in which way the the callbacks and the event loop can
+run concurrently. For the event loop, we use a fixed array. For a
+real-world implementation, you should use a dynamically sized
+structure because the number of file descriptors needed for a crypto
+operation in @acronym{GPGME} is not predictable.
+
+@example
+#include <pthread.h>
+#include <sys/types.h>

+
+/* The following structure holds the result of a crypto operation. */

+@cindex GPL, GNU General Public License
+@center Version 2, June 1991

+Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc.
+59 Temple Place -- Suite 330, Boston, MA 02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+@end display
+
+@appendixsubsec Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software---to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+@iftex
+@appendixsubsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+@end iftex
+@ifinfo
+@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+@end ifinfo
+
+@enumerate
+@item
+This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The ``Program'', below,
+refers to any such program or work, and a ``work based on the Program''
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term ``modification''.) Each licensee is addressed as ``you''.
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+@item
+You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+@item
+You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+@enumerate a
+@item
+You must cause the modified files to carry prominent notices
+stating that you changed the files and the date of any change.
+
+@item
+You must cause any work that you distribute or publish, that in
+whole or in part contains or is derived from the Program or any
+part thereof, to be licensed as a whole at no charge to all third
+parties under the terms of this License.
+
+@item
+If the modified program normally reads commands interactively
+when run, you must cause it, when started running for such
+interactive use in the most ordinary way, to print or display an
+announcement including an appropriate copyright notice and a
+notice that there is no warranty (or else, saying that you provide
+a warranty) and that users may redistribute the program under
+these conditions, and telling the user how to view a copy of this
+License. (Exception: if the Program itself is interactive but
+does not normally print such an announcement, your work based on
+the Program is not required to print an announcement.)
+@end enumerate
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+@item
+You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+@enumerate a
+@item
+Accompany it with the complete corresponding machine-readable
+source code, which must be distributed under the terms of Sections
+1 and 2 above on a medium customarily used for software interchange; or,
+
+@item
+Accompany it with a written offer, valid for at least three
+years, to give any third party, for a charge no more than your
+cost of physically performing source distribution, a complete
+machine-readable copy of the corresponding source code, to be
+distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange; or,
+
+@item
+Accompany it with the information you received as to the offer
+to distribute corresponding source code. (This alternative is
+allowed only for noncommercial distribution and only if you
+received the program in object code or executable form with such
+an offer, in accord with Subsection b above.)
+@end enumerate
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+@item
+You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+@item
+You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+@item
+Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+@item
+If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+@item
+If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+@item
+The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and ``any
+later version'', you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+@item
+If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.

+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

+@unnumberedsec How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the ``copyright'' line and a pointer to where the full notice is found.
+
+@smallexample
+@var{one line to give the program's name and an idea of what it does.}
+Copyright (C) 19@var{yy} @var{name of author}
+
+This program is free software; you can redistribute it and/or
+modify it under the terms of the GNU General Public License
+as published by the Free Software Foundation; either version 2
+of the License, or (at your option) any later version.
+
+This program is distributed in the hope that it will be useful,
+but WITHOUT ANY WARRANTY; without even the implied warranty of
+MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along
+with this program; if not, write to the Free Software Foundation, Inc.,
+59 Temple Place, Suite 330, Boston, MA 02111-1307, USA.
+@end smallexample
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+@smallexample
+Gnomovision version 69, Copyright (C) 19@var{yy} @var{name of author}
+Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
+type `show w'. This is free software, and you are welcome
+to redistribute it under certain conditions; type `show c'
+for details.
+@end smallexample
+
+The hypothetical commands @samp{show w} and @samp{show c} should show
+the appropriate parts of the General Public License. Of course, the
+commands you use may be called something other than @samp{show w} and
+@samp{show c}; they could even be mouse-clicks or menu items---whatever
+suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a ``copyright disclaimer'' for the program, if
+necessary. Here is a sample; alter the names:
+
+@smallexample
+@group
+Yoyodyne, Inc., hereby disclaims all copyright
+interest in the program `Gnomovision'
+(which makes passes at compilers) written
+by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+ This patch has gotten a bit large... mmh. The main thing that
+ happens here is that error values are now not determined in the
+ operation function after gpgme_wait completed, but in the status
+ handler when EOF is received. It should always be the case that
+ either an error is flagged or EOF is received, so that after a
+ gpgme_wait you should never have the situation that no error is
+ flagged and EOF is not received. One problem is that the engine
+ status handlers don't have access to the context, a horrible
+ kludge works around this for now. All errors that happen during a
+ pending operation should be catched and reported in ctx->error,
+ including out-of-core and cancellation. This rounds up neatly a
+ couple of loose ends, and makes it possible to pass up any errors
+ in the communication with the backend as well. As a bonus, there
+ will be a function to access gpgme->wait, so that the operations
+ can truly be implemented with their _start function.
