NAME

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

CCHandle (input)
The handle that describes the context of this cryptographic operation used to link to the CSP-managed information.

Signature (input)
A pointer to a CSSM_DATA structure which contains the starting address for the signature to verify against and the length of the signature in bytes.

SPI PARAMETERS

CSPHandle (input)
The handle that describes the add-in cryptographic service provider module used to perform up calls to CSSM for the memory functions managed by CSSM.

DESCRIPTION

This function finalizes the staged verify data function. 

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. 

ERRORS

Errors are described in the CDSA technical standard.  See CDSA_intro(3).
