VerifyDataFinal, CSSM_VerifyDataFinal, CSP_VerifyDataFinal - Finalize
the staged verify data (CDSA)
SYNOPSIS
# include <cdsa/cssm.h>
API: CSSM_RETURN CSSMAPI CSSM_VerifyDataFinal (CSSM_CC_HANDLE CCHandle,
const CSSM_DATA *Signature) SPI: CSSM_BOOL CSSMCSPI CSP_VerifyDataFinal
(CSSM_CSP_HANDLE CSPHandle, CSSM_CC_HANDLE CCHandle, const CSSM_DATA
*Signature)
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. A pointer to a CSSM_DATA
structure which contains the starting address for the signature to ver‐
ify against and the length of the signature in bytes.
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.
DESCRIPTION
This function finalizes the staged verify data function.
RETURN VALUE

condition. The value CSSM_OK indicates success. All other values repre‐
sent an error condition.
