56 msva-query-agent - query a Monkeysphere Validation Agent
60 msva-query-agent CONTEXT PEER PKC_TYPE [PEER_TYPE] < /path/to/public_key_carrier
64 msva-query-agent validates certificates for a given use by querying a
65 running Monkeysphere Validation Agent.
69 msva-query-agent reads a certificate from standard input, and posts it
70 to the running Monkeysphere Validation Agent. The return code
71 indicates the validity (as determined by the agent) of the certificate
72 for the specified purpose. The agent's return message (if any) is
75 The first three command-line arguments are all required, supplied in
82 Context in which the certificate is being validated (e.g. 'https',
87 The name of the intended peer. When validating a certificate for a
88 service, supply the host's full DNS name (e.g. 'foo.example.net')
92 The format of public key carrier data provided on standard input
93 (e.g. 'x509der', 'x509pem', 'opensshpubkey', 'rfc4716')
97 The fourth argument is optional:
103 The type of peer we are inquiring about (e.g. 'client', 'server')
109 If the certificate is valid for the requested peer in the given
110 context, the return code is 0. Otherwise, the return code is 1.
112 =head1 ENVIRONMENT VARIABLES
114 msva-query-agent's behavior is controlled by environment variables:
118 =item MONKEYSPHERE_VALIDATION_AGENT_SOCKET
120 Socket over which to query the validation agent. If unset, the
121 default value is 'http://localhost:8901'.
125 Log messages about its operation to stderr. MSVA_LOG_LEVEL controls
126 its verbosity, and should be one of (in increasing verbosity): silent,
127 quiet, fatal, error, info, verbose, debug, debug1, debug2, debug3.

134 Communications with the Monkeysphere Validation Agent are in the form
135 of JSON requests over plain HTTP. Responses from the agent are also
