Get the formats of the encoded bytes : Key Generator « Security « Java Tutorial


public class Main {
  public static void main(String[] argv) throws Exception {
    String algorithm = "DSA"; // or RSA, DH, etc.

    // Generate a 1024-bit Digital Signature Algorithm (DSA) key pair
    KeyPairGenerator keyGen = KeyPairGenerator.getInstance(algorithm);
    KeyPair keypair = keyGen.genKeyPair();
    PrivateKey privateKey = keypair.getPrivate();
    PublicKey publicKey = keypair.getPublic();
    String format = privateKey.getFormat(); // PKCS#8
    format = publicKey.getFormat(); // X.509
