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)
DESCRIPTIONThis 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 VALUEA CSSM_RETURN value indicating success or specifying a particular
error condition. The value CSSM_OK indicates success. All other
values represent an error condition. ERRORSErrors are described in the CDSA Technical Standard.
