             (CertificateVerifier verifier, List<X509CRL> crls)

crls - a list of CRLs

Method Details

verify

             public List<VerificationOK> verify
             (X509Certificate signCert, X509Certificate issuerCert, Date signDate) throws GeneralSecurityException
            

Deprecated.

Verifies whether a valid CRL is found for the certificate. If this method returns false, it doesn't mean the certificate isn't valid. It means we couldn't verify it against any CRL that was available.

Overrides:

verify in class RootStoreVerifier

Parameters:

signCert - the certificate that needs to be checked

issuerCert - its issuer

signDate - the date the certificate needs to be valid

Returns:

a list of VerificationOK objects. The list will be empty if the certificate couldn't be verified.

Throws:

GeneralSecurityException - thrown if the certificate has expired, isn't valid yet, or if an exception has been thrown in Certificate#verify.
