NAME

CSSM_CL_CrlSign, CL_CrlSign — Sign a CRL (CDSA)

SYNOPSIS

# include <cssm.h>

API:
CSSM_RETURN CSSMAPI CSSM_CL_CrlSign
(CSSM_CL_HANDLE CLHandle,
CSSM_CC_HANDLE CCHandle,
const CSSM_DATA *UnsignedCrl,
const CSSM_FIELD *SignScope,
uint32 ScopeSize,
CSSM_DATA_PTR SignedCrl)
SPI:
CSSM_RETURN CSSMCLI CL_CrlSign
(CSSM_CL_HANDLE CLHandle,
CSSM_CC_HANDLE CCHandle,
const CSSM_DATA *UnsignedCrl,
const CSSM_FIELD *SignScope,
uint32 ScopeSize,
CSSM_DATA_PTR SignedCrl)

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`)		The handle that describes the context of this cryptographic operation.
`UnsignedCrl` (`input`)
		A pointer to the CSSM_DATA structure containing the CRL to be signed.
`SignScope` (input/optional)
		A pointer to the CSSM_FIELD array containing the tag/value pairs of the fields to be signed. If the signing scope is null, the Certificate Library module includes a default set of CRL fields in the signing process.
`ScopeSize` (`input`)
		The number of entries in the sign scope list. If the signing scope is not specified, the input scope size must be zero.
`SignedCrl` (`output`)
		A pointer to the CSSM_DATA structure containing the signed CRL. The `SignedCrl->Data` is allocated by the service provider and must be deallocated by the application.

DESCRIPTION

This function signs a CRL using the private key and signing algorithm specified in the CCHandle parameter. The result is a signed, encoded certificate revocation list in SignedCrl. The unsigned CRL is specified in the input UnsignedCrl. The UnsignedCrl is constructed using the CSSM_CL_CrlCreateTemplate(), CSSM_CL_CrlSetFields(), CSSM_CL_CrlAddCert(), and CSSM_CL_CrlRemoveCert() functions (for the CSSM API), or their CL SPI equivalents.

The CCHandle must be context created using the function CSSM_CSP_CreateSignatureContext() (CSSM API), or CSP_CreateSignatureContext() (SPI). The context must specify the Cryptographic Services Provider module, the signing algorithm, and the signing key that must be used to perform this operation. The context must also provide the passphrase or a callback function to obtain the passphrase required to access and use the private key.

The fields included in the signing operation are identified by the OIDs in the optional SignScope array.

Once the CRL has been signed it cannot be modified. This means that entries cannot be added or removed from the CRL through application of the CSSM_CL_CrlAddCert() or CSSM_CL_CrlRemoveCertCSSM_CL_CrlRemoveCert() (or their CL SPI equivalent operations. A signed CRL can be verified, applied to a data store, and searched for values.

The memory for the SignedCrl->Data output is allocated by the service provider using the calling application's memory management routines. The application must deallocate the memory.

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.
