RFC3280CertPathUtilities

Checks a certificate if it is revoked.

If the DP includes cRLIssuer, then verify that the issuer field in the complete CRL matches cRLIssuer in the DP and that the complete CRL contains an issuing distribution point extension with the indirectCRL boolean asserted. Otherwise, verify that the CRL issuer matches the certificate issuer.

If the complete CRL includes an issuing distribution point (IDP) CRL extension check the following:

(i) If the distribution point name is present in the IDP CRL extension and the distribution field is present in the DP, then verify that one of the names in the IDP matches one of the names in the DP. If the distribution point name is present in the IDP CRL extension and the distribution field is omitted from the DP, then verify that one of the names in the IDP matches one of the names in the cRLIssuer field of the DP.

(ii) If the onlyContainsUserCerts boolean is asserted in the IDP CRL extension, verify that the certificate does not include the basic constraints extension with the cA boolean asserted.

(iii) If the onlyContainsCACerts boolean is asserted in the IDP CRL extension, verify that the certificate includes the basic constraints extension with the cA boolean asserted.

(iv) Verify that the onlyContainsAttributeCerts boolean is not asserted.

If use-deltas is set, verify the issuer and scope of the delta CRL.

Obtain and validate the certification path for the complete CRL issuer. If a key usage extension is present in the CRL issuer's certificate, verify that the cRLSign bit is set.
