Usage

From source file:MainClass.java

public static void main(String[] args) throws Exception {
    Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());

    KeyPair pair = generateRSAKeyPair();

    ByteArrayOutputStream bOut = new ByteArrayOutputStream();
    bOut.write(generateV1Certificate(pair).getEncoded());
    bOut.close();//from  ww  w  .j  a  v a  2s .  c  o  m

    InputStream in = new ByteArrayInputStream(bOut.toByteArray());

    CertificateFactory fact = CertificateFactory.getInstance("X.509", "BC");

    X509Certificate x509Cert;
    Collection collection = new ArrayList();

    while ((x509Cert = (X509Certificate) fact.generateCertificate(in)) != null) {
        collection.add(x509Cert);
    }

    Iterator it = collection.iterator();
    while (it.hasNext()) {
        System.out.println("version: " + ((X509Certificate) it.next()).getVersion());
