.Sh DESCRIPTION
|
|
Verifies that a cryptographic MIC,
|
|
contained in the token parameter,
|
|
fits the supplied message.
|
|
The
|
|
.Fa qop_state
|
|
parameter allows a message recipient to determine the strength of
|
|
protection that was applied to the message.
|
|
.Pp
|
|
Since some application-level protocols may wish to use tokens emitted
|
|
by
|
|
.Fn gss_wrap
|
|
to provide "secure framing",
|
|
implementations must support the calculation and verification of MICs
|
|
over zero-length messages.
|
|
.Pp
|
|
The
|
|
.Fn gss_verify
|
|
routine is an obsolete variant of
|
|
.Fn gss_verify_mic .
|
|
It is provided for backwards
|
|
compatibility with applications using the GSS-API V1 interface.
|
|
A distinct entrypoint (as opposed to #define) is provided,
|
|
both to allow GSS-API V1 applications to link
|
|
and to retain the slight parameter type differences between the
|
|
obsolete versions of this routine and its current form.
|
|
.Sh PARAMETERS
|
|
.Bl -tag
|
|
.It minor_status
|
|
Mechanism specific status code.
|
|
.It context_handle
|
|
Identifies the context on which the message arrived.
|
|
.It message_buffer
|
|
Message to be verified.
|
|
.It token_buffer
|
|
Token associated with message.
|
|
.It qop_state
|
|
Quality of protection gained from MIC.

|
|
.Bl -tag
|
|
.It GSS_S_COMPLETE
|
|
Successful completion
|
|
.It GSS_S_DEFECTIVE_TOKEN
|
|
The token failed consistency checks
|
|
.It GSS_S_BAD_SIG
|
|
The MIC was incorrect
|
|
.It GSS_S_DUPLICATE_TOKEN
|
|
The token was valid,
|
|
and contained a correct MIC for the message,
|
|
but it had already been processed
|
|
.It 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
|
|
.It 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.
|
|
.It 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
|
|
.It GSS_S_CONTEXT_EXPIRED
|
|
The context has already expired
|
|
.It GSS_S_NO_CONTEXT
|
|
The context_handle parameter did not identify a valid context
