TP_CrlVerify(3)


NAME

  TP_CrlVerify, CSSM_TP_CrlVerify - Verify integrity of the certificate
  revocation list (CDSA)


SYNOPSIS

  # include <cdsa/cssm.h>

       API:
       CSSM_RETURN CSSMAPI CSSM_TP_CrlVerify
       (CSSM_TP_HANDLE TPHandle,
       CSSM_CL_HANDLE CLHandle,
       CSSM_CSP_HANDLE CSPHandle,
       const CSSM_ENCODED_CRL *CrlToBeVerified,
       const CSSM_CERTGROUP *SignerCertGroup,
       const CSSM_TP_VERIFY_CONTEXT *VerifyContext,
       CSSM_TP_VERIFY_CONTEXT_RESULT_PTR RevokerVerifyResult)
       SPI:
       CSSM_RETURN CSSMTPI TP_CrlVerify
       (CSSM_TP_HANDLE TPHandle,
       CSSM_CL_HANDLE CLHandle,
       CSSM_CSP_HANDLE CSPHandle,
       const CSSM_ENCODED_CRL *CrlToBeVerified,
       const CSSM_CERTGROUP *SignerCertGroup,
       const CSSM_TP_VERIFY_CONTEXT *VerifyContext,
       CSSM_TP_VERIFY_CONTEXT_RESULT_PTR RevokerVerifyResult)


LIBRARY

  Common Security Services Manager library (libcssm.so)


PARAMETERS

  TPHandle (input)
	  The handle that describes the add-in trust policy module used to
	  perform this function.

  CLHandle (input/optional)
	  The handle that describes the add-in certificate library module
	  that can be used to manipulate the certificates to be verified. If
	  no certificate library module is specified, the TP module uses an
	  assumed CL module, if required.

  CSPHandle (input/optional)
	  The handle referencing a Cryptographic Service Provider to be used
	  to verify signatures on the signer's certificate and on the CRL.
	  The TP module is responsible for creating the cryptographic context
	  structure required to perform the verification operation. If no CSP
	  is specified, the TP module uses an assumed CSP to perform the
	  operations.

  CrlToBeVerified (input)
	  A pointer to the CSSM_DATA structure containing a signed
	  certificate revocation list to be verified. The CRL type and
	  encoding are included in this structure.

  SignerCertGroup (input)
	  A pointer to the CSSM_CERTGROUP structure containing one or more
	  related certificates that paretially or fully represent the signer
	  of the certificate revocation list. The first certificate in the
	  group is the target certificate representing the CRL signer. Use of
	  subsequent certificates is specific to the trust domain. For
	  example, in a hierarchical trust model subsequent members are
	  intermediate certificates of a certificate chain - the caller can
	  specify additional points of trust represented by anchor
	  certificates in the VerifyContext. The trust policy module can use
	  these additional points of trust in the verification process.

  VerifyContext (input/optional)
	  A structure containing credentials, policy information, and
	  contextual information to be used in the verification process. All
	  of the input values in the context are optional. The service
	  provider can define default values or can attempt to operate
	  without input for all the other fields of this input structure.
	  The operation can fail if a necessary input value is omitted and
	  the service module can not define an appropriate default value

  RevokerVerifyResult (output/optional)
	  A pointer to a structure containing information generation during
	  the verification process. The information can include:

	  Evidence	      .PP (output/optional)
			      .PP (output/optional)

	  NumberOfEvidences


DESCRIPTION

  This function verifies the integrity of the certificate revocation list and
  determines whether it is trusted. The conditions for trust are part of the
  trust policy module. It can include conditions such as validity of the
  signer's certificate, verification of the signature on the CRL, the
  identity of the signer, the identity of the sender of the CRL, date the CRL
  was issued, the effective dates on the CRL, and so on.

  The caller can specify additional points of trust represented by anchor
  certificates in the VerifyContext. The trust policy module can use these
  additional points of trust in the verification process.


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 are described in the CDSA technical standard.	See CDSA_intro(3).
