gss_get_mic(3) Library Functions Manual gss_get_mic(3)NAME
gss_get_mic() - calculate a cryptographic message integrity code (MIC) for a message and return in a token
SYNOPSIS
DESCRIPTION
The routine generates a cryptographic message integrity code (MIC) for the supplied message and places the MIC in a token for trans-
fer to the peer application. The qop_req parameter allows a choice between several cryptographic algorithms, if supported by the
chosen mechanism.
Input Parameters
context_handle Specifies the context on which the message is sent.
qop_req Specifies the cryptographic algorithm, or quality of protection. To accept the default quality of protection offered
by the chosen mechanism specify
message_buffer Specifies the message to be protected.
Output Parameters
msg_token Buffer to receive the sealed message.
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 context has already expired.
The context is recognized but the associated
credentials have expired.
The context identified in the
context_handle parameter was not valid.
The specified QOP is not supported by the mechanism.

gss_get_mic - calculate a cryptographic message
SYNOPSIS
cc -flag ... file ...-lgss [library ...]
#include <gssapi/gssapi.h>
OM_uint32 gss_get_mic(OM_uint32 *minor_status, const gss_ctx_id_t context_handle, gss_qop_t qop_req, const gss_buffer_t message_buffer,
gss_buffer_t msg_token);
DESCRIPTION
The gss_get_mic() function generates a cryptographic MIC for the supplied message, and places the MIC in a token for transfer to the peer
application. The qop_req parameter allows a choice between several cryptographic algorithms, if supported by the chosen mechanism.
Since some application-level protocols may wish to use tokens emitted by gss_wrap(3GSS) to provide secure framing, the GSS-API allows MICs
to be derived from zero-length messages.
PARAMETERS
The parameter descriptions for gss_get_mic() follow:
minor_status The status code returned by the underlying mechanism.
context_handle Identifies the context on which the message will be sent.
qop_req Specifies the requested quality of protection. Callers are encouraged, on portability grounds, to accept the
default quality of protection offered by the chosen mechanism, which may be requested by specifying
GSS_C_QOP_DEFAULT for this parameter. If an unsupported protection strength is requested, gss_get_mic() will return
a major_status of GSS_S_BAD_QOP.
message_buffer The message to be protected.
msg_token The buffer to receive the token. Storage associated with this message must be freed by the application after use
with a call to gss_release_buffer(3GSS).
ERRORS
gss_get_mic() may return the following status codes:
GSS_S_COMPLETE Successful completion.
GSS_S_CONTEXT_EXPIRED The context has already expired.
GSS_S_NO_CONTEXT The context_handle parameter did not identify a valid context.
GSS_S_BAD_QOP The specified QOP is not supported by the mechanism.
GSS_S_FAILURE The underlying mechanism detected an error for which no specific GSS status code is defined. The mecha-
nism-specific status code reported by means of the minor_status parameter details the error condition.
