80 msva-query-agent - query a Monkeysphere Validation Agent

92 msva-query-agent validates certificates for a given use by querying a
93 running Monkeysphere Validation Agent.
97 msva-query-agent reads a certificate from standard input, and posts it
98 to the running Monkeysphere Validation Agent. The return code
99 indicates the validity (as determined by the agent) of the certificate
100 for the specified purpose. The agent's return message (if any) is
103 The various arguments are:
109 Context in which the certificate is being validated (e.g. 'https',
114 The name of the intended peer. When validating a certificate for a
115 service, supply the host's full DNS name (e.g. 'foo.example.net')
119 The format of public key carrier data provided on standard input
120 (e.g. 'x509der', 'x509pem', 'opensshpubkey', 'rfc4716', 'openpgp4fpr')
124 The type of peer we are inquiring about (e.g. 'client', 'server',
125 'peer'). This argument is optional and defaults will be used (based
126 on CONTEXT) if it is not supplied.
130 This is the actual public key carrier data itself. If less than five
131 arguments are given, then the PKC_DATA is expected on stdin. If five
132 arguments are given, the fifth argument is interpreted as the
133 PKC_DATA. This is likely only useful for supplying an OpenPGP
134 fingerprint with the 'openpgp4fpr' type.
140 If the certificate is valid for the requested peer in the given
141 context, the return code is 0. Otherwise, the return code is 1.
143 =head1 ENVIRONMENT VARIABLES
145 msva-query-agent's behavior is controlled by environment variables:
149 =item MONKEYSPHERE_VALIDATION_AGENT_SOCKET
151 Socket over which to query the validation agent. If unset, the
152 default value is 'http://localhost:8901'.
156 Log messages about its operation to stderr. MSVA_LOG_LEVEL controls
157 its verbosity, and should be one of (in increasing verbosity): silent,
158 quiet, fatal, error, info, verbose, debug, debug1, debug2, debug3.
163 =head1 COMMUNICATION PROTOCOL DETAILS
165 Communications with the Monkeysphere Validation Agent are in the form
166 of JSON requests over plain HTTP. Responses from the agent are also
167 JSON objects. For details on the structure of the requests and
168 responses, please see
