member this.NonCriticalExtensionOIDs : System.Collections.Generic.ICollection<string>

Property Value

ICollection<String>

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

Attributes: RegisterAttribute

Remarks

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.

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)
        for (String oid : nonCritSet) {
            System.out.println(oid);
        }
}
