CL_CrlVerify

NAME

  CL_CrlVerify,
  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.  See CDSA.
