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