CSSM_BOOL CSSMAPI CSSM_CL_CrlVerify (CSSM_CL_HANDLE CLHandle, CSSM_CC_HANDLE CCHandle, const CSSM_DATA_PTR CrlToBeVerified, const CSSM_DATA_PTR SignerCert, const CSSM_FIELD_PTR VerifyScope, uint32 ScopeSize)
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.
- CLHandle (input)
The handle that describes the add-in certificate library module used to perform this function.
- CCHandle (input)
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)
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.
A CSSM_TRUE return value signifies that the certificate revocation list verifies successfully. When CSSM_FALSE is returned, either the CRL verified unsuccessfully or an error has occurred. Use CSSM_GetError to obtain the error code.
Invalid CL handle.
Invalid Context Handle.
Invalid CRL pointer.
Verify scope is invalid.
Not enough memory to allocate the CRL.
Unable to verify CRL.
