CL_CertVerifyWithKey

NAME

  CL_CertVerifyWithKey,
  CSSM_CL_CertVerifyWithKey - Verify with a key (CDSA)

SYNOPSIS

  # include <cssm.h>

  API:
       CSSM_RETURN CSSMAPI CSSM_CL_CertVerifyWithKey
       (CSSM_CL_HANDLE CLHandle,
       CSSM_CC_HANDLE CCHandle,
       const CSSM_DATA *CertToBeVerified)

  SPI:
       CSSM_RETURN CSSMCLI CL_CertVerifyWithKey
       (CSSM_CL_HANDLE CLHandle,
       CSSM_CC_HANDLE CCHandle,
       const CSSM_DATA *CertToBeVerified)

LIBRARY

  Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)

PARAMETERS

  CLHandle (input)
          The handle that describes the certificate library service module
          used to perform this function.

  CCHandle (input)
          A signature verification context defining the CSP, verification
          algorithm, and public key that must be used to perform the
          operation.

  CertToBeVerified (input)
          A signed certificate whose signature is to be verified.

DESCRIPTION

  This function verifies that the CertToBeVerified parameter was signed
  using a specific private key and that the certificate has not been
  altered since it was signed using that private key. The public key
  corresponding to the private signing key is used in the verification
  process.

  The CCHandle, must be a signature verification context created using
  the function CSSM_CSP_CreateSignatureContext() (CSSM API), or
  CSP_CreateSignatureContext() (SPI). The context must specify the
  Cryptographic Services Provider (CSP) module, the verification
  algorithm, and the public verification key that must be used to
  perform this operation.

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.

       CSSMERR_CL_INVALID_CONTEXT_HANDLE
       CSSMERR_CL_INVALID_CERT_POINTER
       CSSMERR_CL_UNKNOWN_FORMAT
