Examples of java.security.MessageDigest.update()

java.security.MessageDigest.update()
Updates the digest using the specified byte. @param input the byte with which to update the digest.

        peer.keyServer=false;




        MessageDigest digest=MessageDigest.getInstance("MD5");
        digest.reset();
        digest.update(server.getDesKey().getEncoded());


        String symVersion=new String(digest.digest(), "UTF-8");


        // encrypt and send an initial message to peer
        Cipher cipher=server.getSymEncodingCipher();
