gss_verify_mic(3)					     gss_verify_mic(3)

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
       receiving 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 mecha‐
			     nism.

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.
