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);
}

Set<String> critSet = cert.getCriticalExtensionOIDs();
if (critSet != null && !critSet.isEmpty()) {
    System.out.println("Set of critical extensions:");
    for (String oid : critSet) {
        System.out.println(oid);
    }
}

Returns:Set<String>

a Set (or an empty Set if none are marked critical) of the extension OID strings for extensions that are marked critical. If there are no extensions present at all, then this method returns null.

Doc from java.security.cert.X509Extension.getNonCriticalExtensionOIDs.

Gets a Set of the OID strings for the extension(s) marked NON-CRITICAL in the certificate/CRL managed by the object implementing this interface. Here is sample code to get a Set of non-critical extensions from an X509CRL revoked certificate entry and print the OIDs:

CertificateFactory cf = null;
X509CRL crl = null;
try (InputStream inStrm = new FileInputStream("DER-encoded-CRL")) {
    cf = CertificateFactory.getInstance("X.509");
    crl = (X509CRL)cf.generateCRL(inStrm);
}

byte[] certData = <DER-encoded certificate data>
ByteArrayInputStream bais = new ByteArrayInputStream(certData);
X509Certificate cert = (X509Certificate)cf.generateCertificate(bais);
X509CRLEntry badCert =
             crl.getRevokedCertificate(cert.getSerialNumber());

if (badCert != null) {
    Set<String> nonCritSet = badCert.getNonCriticalExtensionOIDs();
    if (nonCritSet != null)

@Override

Implements abstract java.security.cert.X509CRL.getRevokedCertificate.

Doc from java.security.cert.X509CRL.getRevokedCertificate.

Gets the CRL entry, if any, with the given certificate serialNumber.

Parameters

serialNumber:BigInteger

Annotations

@Override

Overrides java.security.cert.X509CRL.getRevokedCertificate.

Doc from java.security.cert.X509CRL.getRevokedCertificate.

Get the CRL entry, if any, for the given certificate.

This method can be used to lookup CRL entries in indirect CRLs, that means CRLs that contain entries from issuers other than the CRL issuer. The default implementation will only return entries for certificates issued by the CRL issuer. Subclasses that wish to support indirect CRLs should override this method.

Parameters

certificate:X509Certificate

the certificate for which a CRL entry is to be looked up

Returns:X509CRLEntry

the entry for the given certificate, or null if no such entry exists in this CRL.

Annotations
