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 the message.
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 valid context.
