       Bugs or feature requests for msva-perl and  associated  tools  should  be  filed  with  the  Monkeysphere
       project's bug tracker at https://labs.riseup.net/code/projects/monkeysphere/issues/

       Communications with the Monkeysphere Validation Agent are in the form of JSON requests over  plain  HTTP.
       Responses  from  the  agent  are  also  JSON  objects.   For details on the structure of the requests and
       responses, please see http://web.monkeysphere.info/validation-agent/protocol

       msva-query-agent's behavior is controlled by environment variables:

       MONKEYSPHERE_VALIDATION_AGENT_SOCKET
           Socket  over  which  to  query  the   validation   agent.    If   unset,   the   default   value   is
           'http://127.0.0.1:8901'.

       MSVA_LOG_LEVEL
           Log messages about its operation to stderr.  MSVA_LOG_LEVEL controls its verbosity, and should be one
           of  (in  increasing  verbosity):  silent,  quiet, fatal, error, info, verbose, debug, debug1, debug2,
           debug3.  Default is 'error'.

       If  the  certificate  is  valid  for  the  requested  peer  in  the  given context, the return code is 0.
       Otherwise, the return code is 1.

       msva-query-agent --version

       msva-query-agent reads a certificate from standard input, and posts it to the running Monkeysphere
       Validation Agent.  The return code indicates the validity (as determined by the agent) of the certificate
       for the specified purpose.  The agent's return message (if any) is emitted on stdout.

       The various arguments are:

       CONTEXT
           Context in which the certificate is being validated (e.g. 'https', 'ssh', 'ike')

       PEER
           The  name  of the intended peer.  When validating a certificate for a service, supply the host's full
           DNS name (e.g.  'foo.example.net')

       PKC_TYPE
           The format of public key  carrier  data  provided  on  standard  input  (e.g.  'x509der',  'x509pem',
           'opensshpubkey', 'rfc4716', 'openpgp4fpr')

       PEER_TYPE
           The type of peer we are inquiring about (e.g. 'client', 'server', 'peer').  This argument is optional
           and defaults will be used (based on CONTEXT) if it is not supplied.

       PKC_DATA
           This  is  the actual public key carrier data itself.  If less than five arguments are given, then the
           PKC_DATA is expected on stdin.  If five arguments are given, the fifth argument is interpreted as the
           PKC_DATA.  This is likely only useful for supplying an OpenPGP  fingerprint  with  the  'openpgp4fpr'
           type.
