sun.security.internal.interfaces.TlsMasterSecret
An SSL/TLS master secret key. It is a SecretKey that optionally contains protocol version information that is used to detect version rollback attacks during the SSL/TLS handshake.
Implementation of this interface are returned by the generateKey() method of KeyGenerators of the type "TlsMasterSecret". @since 1.6 @author Andreas Sterbenz @deprecated Sun JDK internal use only --- WILL BE REMOVED in Dolphin (JDK 7)

                KeyGenerator kg = KeyGenerator.getInstance("SunTlsMasterSecret", provider);
                SecretKey premasterKey = new SecretKeySpec(premaster, algorithm);
                TlsMasterSecretParameterSpec spec = new TlsMasterSecretParameterSpec
                    (premasterKey, protoMajor, protoMinor, clientRandom, serverRandom);
                kg.init(spec);
                TlsMasterSecret key = (TlsMasterSecret)kg.generateKey();
                byte[] enc = key.getEncoded();
                if (Arrays.equals(master, enc) == false) {
                    throw new Exception("mismatch line: " + lineNumber);
                }
                if ((preMajor != key.getMajorVersion()) || (preMinor != key.getMinorVersion())) {
                    throw new Exception("version mismatch line: " + lineNumber);
                }
