gss_verify_mic - API function
OM_uint32 gss_verify_mic(OM_uint32 * minor_status, const gss_ctx_id_t
context_handle, const gss_buffer_t message_buffer, const gss_buffer_t
token_buffer, gss_qop_t * qop_state);
OM_uint32 * minor_status
(Integer, modify) Mechanism specific status code.
const gss_ctx_id_t context_handle
(gss_ctx_id_t, read) Identifies the context on
which the message arrived.
const gss_buffer_t message_buffer
(buffer, opaque, read) Message to be verified.
const gss_buffer_t token_buffer
(buffer, opaque, read) Token associated with
gss_qop_t * qop_state
(gss_qop_t, modify, optional) Quality of protection
gained from MIC Specify NULL if not required.
Verifies that a cryptographic MIC, contained in the token parameter,
fits the supplied message. The qop_state parameter allows a message
recipient to determine the strength of protection that was applied to
Since some application-level protocols may wish to use tokens emitted
by gss_wrap() to provide "secure framing", implementations must support
the calculation and verification of MICs over zero-length messages.
‘GSS_S_COMPLETE‘: Successful completion.
‘GSS_S_DEFECTIVE_TOKEN‘: The token failed consistency checks.
‘GSS_S_BAD_SIG‘: The MIC was incorrect.
‘GSS_S_DUPLICATE_TOKEN‘: The token was valid, and contained a correct
MIC for the message, but it had already been processed.
‘GSS_S_OLD_TOKEN‘: The token was valid, and contained a correct MIC for
the message, but it is too old to check for duplication.
‘GSS_S_UNSEQ_TOKEN‘: The token was valid, and contained a correct MIC
for the message, but has been verified out of sequence; a later token
has already been received.
‘GSS_S_GAP_TOKEN‘: The token was valid, and contained a correct MIC for
the message, but has been verified out of sequence; an earlier expected
token has not yet been received.
‘GSS_S_CONTEXT_EXPIRED‘: The context has already expired.
‘GSS_S_NO_CONTEXT‘: The context_handle parameter did not identify a
