NAME

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.

CSSMERR_CL_INVALID_CONTEXT_HANDLE
CSSMERR_CL_INVALID_CERT_POINTER
CSSMERR_CL_UNKNOWN_FORMAT
