PROGRAM:
NAME
msva-query-agent - query a Monkeysphere Validation Agent
SYNOPSIS
msva-query-agent CONTEXT PEER PKC_TYPE [PEER_TYPE] < /path/to/public_key_carrier
msva-query-agent CONTEXT PEER PKC_TYPE PEER_TYPE PKC_DATA
msva-query-agent --version
ABSTRACT
msva-query-agent validates certificates for a given use by querying a running Monkeysphere
Validation Agent.
USAGE
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.
RETURN CODE
If the certificate is valid for the requested peer in the given context, the return code
is 0. Otherwise, the return code is 1.
ENVIRONMENT VARIABLES
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'.
COMMUNICATION PROTOCOL DETAILS
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
