Leave a comment to notice people that this is not secure

Hi
The point I want to raise here is that maybe we can leave a template on the comment to help the user to implement it when using it (e.g.add the checking code on check-client trusted or checkservertrusted).

A unified TLSv1.2 connection will be better since recent research showed that TLSv1.1 had a security issue.

A workable template would like:
`
new X509TrustManager(){
@OverRide
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {

		for (final X509TrustManager trustManager : trustManagers) {
			try {
				trustManager.checkClientTrusted(chain, authType);
				return;
			} catch (final CertificateException e) {
				//LOGGER.debug(e.getMessage(), e);
			}
		}
		throw new CertificateException("None of the TrustManagers trust this certificate chain");

	}

	@Override
	public X509Certificate[] getAcceptedIssuers() {
		for (final X509TrustManager trustManager : trustManagers) {
			final List<X509Certificate> list = Arrays.asList(trustManager.getAcceptedIssuers());
			certificates.addAll(list);
		}
		return certificates.toArray(new X509Certificate[] {});
	}

	@Override
	public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException{
		if (chain == null) {
			throw new IllegalArgumentException("checkServerTrusted:x509Certificate array isnull");
		}

		if (!(chain.length > 0)) {
			throw new IllegalArgumentException("checkServerTrusted: X509Certificate is empty");
		}

		if (!(null != authType && authType.equalsIgnoreCase("RSA"))) {
			throw new CertificateException("checkServerTrusted: AuthType is not RSA");
		}


		try {
			TrustManagerFactory tmf = TrustManagerFactory.getInstance("X509");
			tmf.init((KeyStore) null);
			for (TrustManager trustManager : tmf.getTrustManagers()) {
				((X509TrustManager) trustManager).checkServerTrusted(chain, authType);
			}
		} catch (Exception e) {
			throw new CertificateException(e);
		}


		RSAPublicKey pubkey = (RSAPublicKey) chain[0].getPublicKey();
		String encoded = new BigInteger(1 , pubkey.getEncoded()).toString(16);
		final boolean expected = PUB_KEY.equalsIgnoreCase(encoded);

		if (!expected) {
			throw new CertificateException("checkServerTrusted: Expected public key: "
					+ PUB_KEY + ", got public key:" + encoded);
		}
	}
};
