This code is properly executing in JDK8 but if I try to execute it in JDK7, it is throwing javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated exception. I tried to google the issue. I found that we can write X509TrustManager and X509HostnameVerifier. I tried with these implementations also, but still didn't work. Please suggest me how can I execute it in JDK7. Again if I execute the code with X509TrustManager and X509HostnameVerifier, I am getting "java.net.SocketException: Connection reset"
I just recently researched this and i want to add this - Support for TLS 1.2 first appeared in JDK 7. For compatibility reasons, it is enabled by default on server sockets but disabled on clients. To change it, I wrote following code and it worked for me:
HttpClient base = new DefaultHttpClient();
SSLContext ctx = SSLContext.getInstance("TLSv1.2");
X509TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
X509HostnameVerifier verifier = new X509HostnameVerifier() {
@Override
public void verify(String string, X509Certificate xc) throws SSLException {
}
@Override
public void verify(String string, String[] strings, String[] strings1) throws SSLException {
}
@Override
public boolean verify(String string, SSLSession ssls) {
return true;
}
@Override
public void verify(String arg0, SSLSocket arg1) throws IOException {
}
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new
SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ssf.setHostnameVerifier(verifier);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", ssf, 443));
httpClient = new DefaultHttpClient(ccm, base.getParams());
