VerifyDataInit, CSSM_VerifyDataInit, CSP_VerifyDataInit - Initialize
the staged verify data (CDSA)
SYNOPSIS
# include <cdsa/cssm.h>
API: CSSM_RETURN CSSMAPI CSSM_VerifyDataInit (CSSM_CC_HANDLE CCHandle)
SPI: CSSM_RETURN CSSMCSPI CSP_VerifyDataInit (CSSM_CSP_HANDLE CSPHan‐
dle, CSSM_CC_HANDLE CCHandle, const CSSM_CONTEXT *Context)
LIBRARY
Common Security Services Manager library (libcssm.so)
API PARAMETERS
The handle that describes the context of this cryptographic operation
used to link to the CSP-managed information.
SPI PARAMETERS
The handle that describes the add-in cryptographic service provider
module used to perform up calls to CSSM for the memory functions man‐
aged by CSSM. Pointer to CSSM_CONTEXT structure that describes the
attributes with this context.
DESCRIPTION
This function initializes the staged verify data function.
For staged operations, a combination operation selecting both a digest‐
ing algorithm and a verification algorithm must be specified.
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.
