+(e.g. 'x509der', 'x509pem', 'opensshpubkey', 'rfc4716', 'openpgp4fpr')

+=item 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.
+
+=item 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.
