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