NAME

CSSM_CSP_CreateDigestContext − Create a digest cryptographic context (CDSA)

SYNOPSIS

# include <cdsa/cssm.h>

CSSM_RETURN CSSMAPI CSSM_CSP_CreateDigestContext
(CSSM_CSP_HANDLE CSPHandle,
CSSM_ALGORITHMS AlgorithmID,
CSSM_CC_HANDLE ∗NewContextHandle)

LIBRARY

Common Security Services Manager library (libcssm.so)

PARAMETERS

CSPHandle (input)
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.

AlgorithmID (input)
The algorithm identification number for message digests.

NewContextHandle (output)
Cryptographic context handle.

DESCRIPTION

This function creates a digest cryptographic context, given a handle of a CSP and an algorithm identification number. The cryptographic context handle is returned. The cryptographic context handle can be used to call digest cryptographic functions. 

RETURN VALUE

A CSSM_RETURN value indicating success or specifying a particular error condition. The value CSSM_OK indicates success. All other values represent an error condition.
