CSSM_CSP_CreateDigestContext(3)


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.
