gss_wrap(3) gss gss_wrap(3)
NAME
gss_wrap - API function
SYNOPSIS
#include <gss.h>
OM_uint32 gss_wrap(OM_uint32 * minor_status, const gss_ctx_id_t con‐
text_handle, int conf_req_flag, gss_qop_t qop_req, const gss_buffer_t
input_message_buffer, int * conf_state, gss_buffer_t output_mes‐
sage_buffer);
ARGUMENTS
OM_uint32 * minor_status
(Integer, modify) Mechanism specific status code.
const gss_ctx_id_t context_handle
(gss_ctx_id_t, read) Identifies the context on
which the message will be sent.
int conf_req_flag
(boolean, read) Non-zero - Both confidentiality and
integrity services are requested. Zero - Only integrity
service is
requested.
gss_qop_t qop_req
(gss_qop_t, read, optional) Specifies required quality of
protection. A mechanism-specific default may be
requested by
setting qop_req to GSS_C_QOP_DEFAULT. If an unsupported
protection strength is requested, gss_wrap will return a
major_status of GSS_S_BAD_QOP.
const gss_buffer_t input_message_buffer
(buffer, opaque, read) Message to be
protected.
int * conf_state
(boolean, modify, optional) Non-zero -
Confidentiality, data origin authentication and integrity
services have been applied. Zero - Integrity and data
origin
services only has been applied. Specify NULL if not
required.
gss_buffer_t output_message_buffer
(buffer, opaque, modify) Buffer to receive
protected message. Storage associated with this message
must be
freed by the application after use with a call to
gss_release_buffer().
DESCRIPTION
Attaches a cryptographic MIC and optionally encrypts the specified
input_message. The output_message contains both the MIC and the mes‐
sage. The qop_req parameter allows a choice between several crypto‐
graphic algorithms, if supported by the chosen mechanism.
Since some application-level protocols may wish to use tokens emitted
by gss_wrap() to provide "secure framing", implementations must support
the wrapping of zero-length messages.
RETURN VALUE
`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.
