NAME

CSSM_CL_CrlVerify — Verify a signed CRL has not been altered (CDSA)

SYNOPSIS

# include <cssm.h>
API:
CSSM_RETURN CSSMAPI CSSM_CL_CrlVerify
(CSSM_CL_HANDLE CLHandle,
CSSM_CC_HANDLE CCHandle,
const CSSM_DATA *CrlToBeVerified,
const CSSM_DATA *SignerCert,
const CSSM_FIELD *VerifyScope,
uint32 ScopeSize)
SPI:
CSSM_RETURN CSSMCLI CL_CrlVerify
(CSSM_CL_HANDLE CLHandle,
CSSM_CC_HANDLE CCHandle,
const CSSM_DATA *CrlToBeVerified,
const CSSM_DATA *SignerCert,
const CSSM_FIELD *VerifyScope,
uint32 ScopeSize)

LIBRARY

Common Security Services Manager library (cdsa$incssm300_shr.exe)

PARAMETERS

CLHandle (input) 

The handle that describes the add-in Certificate Library module used to perform this function.

CCHandle (input/optional)
  

The handle that describes the context of this cryptographic operation.

CrlToBeVerified (input)
  

A pointer to the CSSM_DATA structure containing the CRL to be verified.

SignerCert (input/optional)
  

A pointer to the CSSM_DATA structure containing the certificate used to sign the CRL.

VerifyScope (input/optional)
  

A pointer to the CSSM_FIELD array containing the tag/value pairs of the fields to be verified. If the verification scope is null, the Certificate Library module assumes that a default set of fields were used in the signing process and those same fields are used in the verification process.

ScopeSize (input)
  

The number of entries in the verify scope list. If the verification scope is not specified, the input value for scope size must be zero.

DESCRIPTION

This function verifies that the signed CRL has not been altered since it was signed by the designated signer. It does this by verifying the digital signature over the fields specified by the VerifyScope parameter.

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.

CSSMERR_CL_INVALID_CONTEXT_HANDLE
CSSMERR_CL_INVALID_CERT_POINTER
CSSMERR_CL_INVALID_CRL_POINTER
CSSMERR_CL_UNKNOWN_FORMAT
CSSMERR_CL_INVALID_FIELD_POINTER
CSSMERR_CL_UNKNOWN_TAG
CSSMERR_CL_INVALID_SCOPE
CSSMERR_CL_INVALID_NUMBER_OF_FIELDS
CSSMERR_CL_SCOPE_NOT_SUPPORTED
CSSMERR_CL_VERIFICATION_FAILURE
