CSSM_CSP_CreateMacContext(3)CSSM_CSP_CreateMacContext(3)NAMECSSM_CSP_CreateMacContext - Create a message authentication code cryp‐
tographic context (CDSA)
SYNOPSIS
# include <cdsa/cssm.h>
CSSM_RETURN CSSMAPI CSSM_CSP_CreateMacContext (CSSM_CSP_HANDLE CSPHan‐
dle, CSSM_ALGORITHMS AlgorithmID, const CSSM_KEY *Key, CSSM_CC_HANDLE
*NewContextHandle)
LIBRARY
Common Security Services Manager library (libcssm.so)
PARAMETERS
The handle that describes the add-in cryptographic service provider
module used to perform this function. If a NULL handle is specified,
CSSM returns error. The algorithm identification number for the MAC
algorithm. The key used to generate a message authentication code.
Caller passes a pointer to a CSSM_KEY structure containing the key.
Cryptographic context handle.
DESCRIPTION
This function creates a message authentication code cryptographic con‐
text, given a handle of a CSP, algorithm identification number, and a
key. The cryptographic context handle is returned. The cryptographic
context handle can be used to call message authentication code func‐
tions.
RETURN VALUE
A CSSM_RETURN value indicating success or specifying a particular error
condition. The value CSSM_OK indicates success. All other values repre‐
sent an error condition.
