.Sh DESCRIPTION
|
|
Converts a message previously protected by
|
|
.Xr gss_wrap 3
|
|
back to a usable form,
|
|
verifying the embedded MIC.
|
|
The
|
|
.Dv conf_state
|
|
parameter indicates whether the message was encrypted;
|
|
the
|
|
.Dv qop_state
|
|
parameter indicates the strength of protection that was used to provide the
|
|
confidentiality and integrity services.
|
|
.Pp
|
|
Since some application-level protocols may wish to use tokens emitted
|
|
by
|
|
.Xr gss_wrap 3
|
|
to provide "secure framing",
|
|
implementations must support the wrapping and unwrapping of
|
|
zero-length messages.
|
|
.Pp
|
|
The
|
|
.Fn gss_unseal
|
|
routine is an obsolete variant of
|
|
.Fn gss_unwrap .
|
|
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 input_message_buffer
|
|
Protected message.
|
|
.It output_message_buffer
|
|
Buffer to receive unwrapped message.
|
|
Storage associated with this buffer must
|
|
be freed by the application after use use
|
|
with a call to
|
|
.Xr gss_release_buffer 3 .
|
|
.It conf_state
|
|
.Bl -tag -width "Non-zero"
|
|
.It Non-zero
|
|
Confidentiality and integrity protection were used.
|
|
.It Zero
|
|
Integrity service only was used.
|
|

.Pp
|
|
Specify NULL if not required.
|
|
.It qop_state
|
|
Quality of protection provided. Specify NULL if not required.

.El
|
|
.Sh RETURN VALUES
|
|
.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.
