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

 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            (output/optional)
           NumberOfEvidences   (output/optional)

 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
   Errors are described in the CDSA technical standard.  See CDSA.
