NAME

       gss_verify_mic() - check a cryptographic message integrity code (MIC) against a message to verify its integrity

SYNOPSIS


DESCRIPTION

       The routine verifies that a cryptographic MIC, contained in the token_buffer parameter, fits the supplied message.  The application receiv-
       ing the message can use the qop_state parameter to check the strength of protection.

   Input Parameters
       context_handle	     Specifies the context on which the message arrived.

       message_buffer	     Specifies the message to be verified.

       token_buffer	     Specifies the token to be associated with the message.

   Output Parameters
       qop_state	     Returns the quality of protection gained from message integrity code (MIC).  Specify NULL if not required.

       minor_status	     Returns a status code from the security mechanism.

STATUS CODES

       The following status codes can be returned:

       The routine was completed successfully.

       The token failed consistency checks.

       The MIC was incorrect.

       The token was valid, and contained a correct
				MIC for the message, but it had already been processed.

       The token was valid, and contained a correct
				MIC for the message, but it is too old.

       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.

       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.

       The context has already expired.

       The routine failed.  Check the
				minor_status parameter for details.

       The context identified in the
				context_handle parameter was not valid.
