public Class X509CRLObject

Overrides java.security.cert.X509CRL.equals.

Returns:boolean

true iff the encoded forms of the two CRLs match, false otherwise.

Implements java.security.cert.X509Extension.getCriticalExtensionOIDs.

Doc from java.security.cert.X509Extension.getCriticalExtensionOIDs.

Gets a Set of the OID strings for the extension(s) marked CRITICAL in the certificate/CRL managed by the object implementing this interface. Here is sample code to get a Set of critical extensions from an X509Certificate and print the OIDs:

X509Certificate cert = null;
try (InputStream inStrm = new FileInputStream("DER-encoded-Cert")) {
    CertificateFactory cf = CertificateFactory.getInstance("X.509");
    cert = (X509Certificate)cf.generateCertificate(inStrm);

    System.out.println("Set of critical extensions:");
    for (String oid : critSet) {
        System.out.println(oid);
    }
}

Returns:Set<E>

X509CRL crl = null;
try (InputStream inStrm = new FileInputStream("DER-encoded-CRL")) {

X509Certificate cert = (X509Certificate)cf.generateCertificate(bais);
X509CRLEntry badCert =
             crl.getRevokedCertificate(cert.getSerialNumber());
