Java SSL Socket Programming

Java SSL Socket Programming - java

I read about the SSLSocket when i had already finished a Chat program with java that use normal ServerSocket.
I am trying to replace the normal ServerSocket with SSlSocket, there is not much on the internet but i found something.
Now my WhServer class look like this:
This class is the one which start the Socket in a selected port, if you need to see other classes i will edit the question:
import java.io.IOException;
import java.net.*;
import javax.net.ServerSocketFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;
public class WhServer extends Thread {
private int port;
private ServerSocket server;
private ChannelsManager manager;
SSLContext context;
SSLSocketFactory sslSf;
public WhServer(int port, ChannelsManager manager) throws IOException {
this.port = port;
this.manager = manager;
}
public void ServerStop() throws IOException{
server.close();
}
public WhServer(int port) throws IOException {
this(port, new ChannelsManager());
}
public int getPort() {
return port;
}
public void run() {
try {
while(true) {
ServerSocketFactory ssf = ServerSocketFactory.getDefault();
server = ssf.createServerSocket(port);
Socket socket = server.accept();
sslSf = context.getSocketFactory();
SSLSocket sslSocket = (SSLSocket) sslSf.createSocket(socket, null,socket.getPort(), false);
sslSocket.setUseClientMode(false);
manager.initialite(socket);
}
} catch(Exception ex) {
ex.printStackTrace();
}
}
}

Firstly, your SSLContext context instance variable is never initialised, so it is null. Nothing specific to SSL or sockets here, it's just a basic Java error: if you try to call anything on this, it will throw an NPE.
Secondly, even if it's not null (for example, you can create a new instance with context = SSLContext.getInstance("TLS"), see SSLContext section of the Java Cryptography Architecture Standard Algorithm Name Documentation as indicated in the SSLContext API doc), you still need to initialise the SSLContext via its init method.
Since you're trying to implement a server, you'll need to provide a non-null keymanager, otherwise you'll get an SSLHandshakeException saying "no cipher suites in common". You can find details about this in this answer for example.
In addition, you don't need to use plain Sockets and upgrade them to SSLSockets after accepting like you do. It's not necessarily wrong, but the following might be easier:
// Assuming you've initialised your SSLContext
SSLServerSocketFactory sslSf = context.getServerSocketFactory();
SSLServerSocket server = (SSLServerSocket) sslSf.createServerSocket(port);
SSLServerSocketFactory ssf = ServerSocketFactory.getDefault();
server = ssf.createServerSocket(port);
SSLSocket socket = (SSLSocket)server.accept();
Your socket coming from an SSLServerSocketFactory will already be in server mode.
Of course, there's generally no need for the factories to be within the while loop.

context is null. nowhere in your code it is being initialized.
Here's a few static methods you can use to initialize it.
http://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLContext.html
static SSLContext getInstance(String protocol)
Returns a SSLContext object that implements the specified secure socket protocol.
static SSLContext getInstance(String protocol, Provider provider)
Returns a SSLContext object that implements the specified secure socket protocol.
static SSLContext getInstance(String protocol, String provider)
Returns a SSLContext object that implements the specified secure socket protocol.
Some valid values for the protocol string are "SSL", "SSLv2", "SSLv3"...
So, first of all, if you intend to keep that "context" variable as a member variable, make it final and initialize it in your constructor like this:
public WhServer(int port, ChannelsManager manager) throws IOException {
this.port = port;
this.manager = manager;
try {
context = SSLContext.getInstance("SSL"); //pick the SSL protocol you need.
} catch (Throwable t) { t.printStackTrace(); }
}

First you need to create SSLContext with below code:
KeyStore keyStore = KeyStore.getInstance("JKS");
keyStore.load(new FileInputStream("test.jks"),"passphrase".toCharArray());
// Create key manager
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance("SunX509");
keyManagerFactory.init(keyStore, "passphrase".toCharArray());
KeyManager[] km = keyManagerFactory.getKeyManagers();
// Create trust manager
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("SunX509");
trustManagerFactory.init(keyStore);
TrustManager[] tm = trustManagerFactory.getTrustManagers();
// Initialize SSLContext
SSLContext sslContext = SSLContext.getInstance("TLSv1");
sslContext.init(km, tm, null);
Replace the test.jks with your own keystore location.
To understand the SSL communication model in Java, you can refer to Java Secure Socket Extension (JSSE) Reference Guide.
A HTTPS client and HTTPS server demo in Java provides a quite demo on how to create SSL client and SSL server in Java.

How to bypass Https SSLHandshakeException with Tomee

I am trying to invoke a WS over SSL, from a tomee 1.6 server, but I get a SSLHandshakeError. The problem is that the certificate is self signed, and is not recognized by my JVM. As it is only for test purpose, and not production, I have been asked to bypass the certificate control.
I read a lot of stuff about how to proceed, and I have written that code :
a class NaiveSSLContext :
package fr.csf.ssl;
import java.security.NoSuchAlgorithmException;
import java.security.NoSuchProviderException;
import java.security.Provider;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
/**
* A factory class which creates an {#link SSLContext} that
* naively accepts all certificates without verification.
*/
public class NaiveSSLContext
{
private NaiveSSLContext()
{}
/**
* Get an SSLContext that implements the specified secure
* socket protocol and naively accepts all certificates
* without verification.
*/
public static SSLContext getInstance( String protocol) throws NoSuchAlgorithmException
{
SSLContext sslCtx = SSLContext.getInstance( protocol);
init( sslCtx);
return sslCtx;
}
/**
* Get an SSLContext that implements the specified secure
* socket protocol and naively accepts all certificates
* without verification.
*/
public static SSLContext getInstance( String protocol, Provider provider) throws NoSuchAlgorithmException
{
SSLContext sslCtx = SSLContext.getInstance( protocol, provider);
init( sslCtx);
return sslCtx;
}
/**
* Get an SSLContext that implements the specified secure
* socket protocol and naively accepts all certificates
* without verification.
*/
public static SSLContext getInstance( String protocol, String provider) throws NoSuchAlgorithmException, NoSuchProviderException
{
SSLContext sslCtx = SSLContext.getInstance( protocol, provider);
init( sslCtx);
return sslCtx;
}
/**
* Set NaiveTrustManager to the given context.
*/
private static void init( SSLContext context)
{
try
{
// Set NaiveTrustManager.
context.init( null, new TrustManager[] { new NaiveTrustManager() }, new java.security.SecureRandom());
System.out.println( "------------- Initialisation du NaiveSSLContext ---------------------");
}
catch( java.security.KeyManagementException e)
{
throw new RuntimeException( "Failed to initialize an SSLContext.", e);
}
}
/**
* A {#link TrustManager} which trusts all certificates naively.
*/
private static class NaiveTrustManager implements X509TrustManager
{
#Override
public X509Certificate[] getAcceptedIssuers()
{
System.out.println( "------------- NaiveTrustManager.getAcceptedIssuers() ---------------------");
return null;
}
#Override
public void checkClientTrusted( X509Certificate[] certs, String authType)
{
System.out.println( "------------- NaiveTrustManager.checkClientTrusted( " + certs.toString() + ", " + authType
+ ") ---------------------");
}
#Override
public void checkServerTrusted( X509Certificate[] certs, String authType)
{
System.out.println( "------------- NaiveTrustManager.checkServerTrusted( " + certs.toString() + ", " + authType
+ ") ---------------------");
}
}
}
and another class NaiveSSLSocketFactory :
package fr.csf.ssl;
import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.NoSuchAlgorithmException;
public class NaiveSSLSocketFactory extends javax.net.ssl.SSLSocketFactory
{
private javax.net.ssl.SSLSocketFactory factory;
public NaiveSSLSocketFactory() throws NoSuchAlgorithmException
{
javax.net.ssl.SSLContext sslCtx = NaiveSSLContext.getInstance( "SSL");
factory = sslCtx.getSocketFactory();
}
private final String[] enabledProtocols = new String[]
{ "SSLv3", "TLSv1" };
#Override
public Socket createSocket( Socket s, String host, int port, boolean autoClose) throws IOException
{
Socket socket = factory.createSocket( s, host, port, autoClose);
((javax.net.ssl.SSLSocket) socket).setEnabledProtocols( enabledProtocols);
return socket;
}
#Override
public Socket createSocket( String host, int port) throws IOException, UnknownHostException
{
Socket socket = factory.createSocket( host, port);
((javax.net.ssl.SSLSocket) socket).setEnabledProtocols( enabledProtocols);
return socket;
}
#Override
public Socket createSocket( InetAddress host, int port) throws IOException
{
Socket socket = factory.createSocket( host, port);
((javax.net.ssl.SSLSocket) socket).setEnabledProtocols( enabledProtocols);
return socket;
}
#Override
public Socket createSocket( String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException
{
Socket socket = factory.createSocket( host, port, localHost, localPort);
((javax.net.ssl.SSLSocket) socket).setEnabledProtocols( enabledProtocols);
return socket;
}
#Override
public Socket createSocket( InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException
{
Socket socket = factory.createSocket( address, port, localAddress, localPort);
((javax.net.ssl.SSLSocket) socket).setEnabledProtocols( enabledProtocols);
return socket;
}
#Override
public String[] getDefaultCipherSuites()
{
String[] cipherSuites = factory.getDefaultCipherSuites();
return cipherSuites;
}
#Override
public String[] getSupportedCipherSuites()
{
String[] cipherSuites = factory.getSupportedCipherSuites();
return cipherSuites;
}
}
The problem is that I can't find out how to make the JVM use my Naive* classes instead of the default ones. I have tried different methods, but neither of them work :
First try :
javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory( new NaiveSSLSocketFactory());
My log traces in the checkClientTruted methods are never displayed. It seems that my NaiveSSLSocketFactory is never called.
2nd try :
java.security.Security.setProperty( "ssl.SocketFactory.provider", new NaiveSSLSocketFactory().getClass().getName());
I experienced a ClassNotFoundException due to a ClassLoader problem, but after this problem was fixed, the same problem remains.
I eventually found a blog where it was said that CXF client had to do a little more configuration stuff :
<http-conf:conduit name="*.http-conduit" >
<http-conf:tlsClientParameters
useHttpsURLConnectionDefaultSslSocketFactory="true"
/>
</http-conf:conduit>
As I use a Tomee1.6 server, my program is a CXF client. So that must be the solution. But where do I have to write this configuration properties ? I can't find any xml file in Tomee, related with CXF. There's only e cxf.properties file, which is nearly empty.

First, Tomcat isn't involved with your consumption of a web service - in fact it's really not involved with with any outbound connections your application is making.
I know of two ways to achieve your desired results provided by CXF in a way that won't affect any other outbound SSL connections running on the same JVM:
add the self-signed certificate to the CXF client's conduit trust
store, or
install a "do-nothing" trust manager to to the CXF
client's TLS parameters
The first method is preferable as the second will trust any endpoint your client connects with.
To implement the first method, create a key store containing the certificate you wish to trust (and for good measure, include any intermediary certificates). Then add this trust store as outlined in CXF handbook section Configuring SSL Support. Your conduit configuration will look something like this:
<http:conduit name="{http://apache.org/hello_world}HelloWorld.http-conduit">
<http:tlsClientParameters>
<sec:trustManagers>
<sec:keyStore type="JKS" password="password"
file="my/file/dir/Truststore.jks"/>
</sec:trustManagers>
</http:tlsClientParameters>
<http:client AutoRedirect="true" Connection="Keep-Alive"/>
</http:conduit>
Note that the conduit name in the example above is obviously just an example. See the update to my answer here regarding another question as how to specify the conduit name. Also note that I did not include a cipher suite filter as I believe it will default to some set of values, which is potentially unsafe if you're using Java 6 or older .. but that's a whole other topic.
Also, you can eschew Spring configuration of CXF entirely and do all of the above programmatically using CXF client APIs.
I also highly suggest using a tool like KeyStore Explorer to extract certificate (and intermediaries) from the target endpoint and import them into your new trust store.
Finally, I would like to point out, in reference to your initial solution, the danger of using JVM-wide installation of things like SSL socket factories and trust managers as supported by the JDK API. There is a possibility of perilous consequences of doing so when running inside of a container supporting multiple applications: you can subvert the security profile of other applications. One of the benefits of using a framework like CXF is that it provides means to customize SSL/TLS configurations for each application client (or server) instance.

generating SSL certificates and hooking an ssl client into them in java

So I have some of the ssl server and client side code. I'm not sure what to put in some of the methods though.
public void client() throws UnknownHostException, IOException{
KeyStore keyStore = KeyStore.getInstance("PKCS12");
FileInputStream stream = new FileInputStream(new File("")); // need correct file
keyStore.load(stream, "Some Password".toCharArray());
// load in the appropriate keystore and truststore for the client
// get the X509KeyManager and X509TrustManager instances
TrustManagerFactory trustManagerFactory =
TrustManagerFactory.getInstance("PKIX", "SunJSSE");
trustManagerFactory.init("NOT SURE WHAT TO PUT HERE");
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(new KeyManager[]{"NOT SURE WHAT TO PUT HERE"},
new TrustManager[]{"NOT SURE WHAT TO PUT HERE"}, null);
SSLSocketFactory socketFactory = sslContext.getSocketFactory();
SSLSocket socket =
(SSLSocket) socketFactory.createSocket("localhost", 25500);
socket.setEnabledProtocols(new String[]{"TLSv1"});
// read from the socket, etc
}
public void server() throws IOException{
// load in the appropriate keystore and truststore for the server
// get the X509KeyManager and X509TrustManager instances
SSLContext sslContext = SSLContext.getInstance("TLS");
// the final null means use the default secure random source
sslContext.init(new KeyManager[]{"NOT SURE WHAT TO PUT HERE"},
new TrustManager[]{"NOT SURE WHAT TO PUT HERE"}, null);
SSLServerSocketFactory serverSocketFactory =
sslContext.getServerSocketFactory();
SSLServerSocket serverSocket =
(SSLServerSocket) serverSocketFactory.createServerSocket(25500);
serverSocket.setNeedClientAuth(true);
// prevent older protocols from being used, especially SSL2 which is insecure
serverSocket.setEnabledProtocols(new String[]{"TLSv1"});
// you can now call accept() on the server socket, etc
}
Also, how do I generate certificates in java "like the code" and print it out to a file and have it use the same certificate over and over again.
Thx for any help.

Change keystore and truststore at runtime [duplicate]

I'm working on a server in a distributed application that has browser clients and also participates in server-to-server communication with a 3rd party.
My server has a CA-signed certificate to let my clients connect using TLS (SSL) communication using HTTP/S and XMPP(secure). That's all working fine.
Now I need to securely connect to a 3rd party server using JAX-WS over HTTPS/SSL. In this communication, my server acts as client in the JAX-WS interation and I've a client certificate signed by the 3rd party.
I tried adding a new keystore through the standard system configuration (-Djavax.net.ssl.keyStore=xyz) but my other components are clearly affected by this. Although my other components are using dedicated parameters for their SSL configuration (my.xmpp.keystore=xxx, my.xmpp.truststore=xxy, ...), it seems that they end up using the global SSLContext. (The configuration namespace my.xmpp. seemed to indicate separation, but it's not the case)
I also tried adding my client certificate into my original keystore, but -again- my other components don't seem to like it either.
I think that my only option left is to programmatically hook into the JAX-WS HTTPS configuration to setup the keystore and truststore for the client JAX-WS interaction.
Any ideas/pointers on how to do this? All information I find either uses the javax.net.ssl.keyStore method or is setting the global SSLContext that -I guess- will end up in the same confilc. The closest I got to something helpful was this old bug report that requests the feature I need: Add support for passing an SSLContext to the JAX-WS client runtime
Any takes?

This one was a hard nut to crack, so for the record:
To solve this, it required a custom KeyManager and a SSLSocketFactory that uses this custom KeyManager to access the separated KeyStore.
I found the base code for this KeyStore and SSLFactory on this excellent blog entry:
how-to-dynamically-select-a-certificate-alias-when-invoking-web-services
Then, the specialized SSLSocketFactory needs to be inserted into the WebService context:
service = getWebServicePort(getWSDLLocation());
BindingProvider bindingProvider = (BindingProvider) service;
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory", getCustomSocketFactory());
Where the getCustomSocketFactory() returns a SSLSocketFactory created using the method mentioned above. This would only work for JAX-WS RI from the Sun-Oracle impl built into the JDK, given that the string indicating the SSLSocketFactory property is proprietary for this implementation.
At this stage, the JAX-WS service communication is secured through SSL, but if you are loading the WSDL from the same secure server () then you'll have a bootstrap problem, as the HTTPS request to gather the WSDL will not be using the same credentials than the Web Service. I worked around this problem by making the WSDL locally available (file:///...) and dynamically changing the web service endpoint: (a good discussion on why this is needed can be found in this forum)
bindingProvider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, webServiceLocation);
Now the WebService gets bootstrapped and is able to communicate through SSL with the server counterpart using a named (alias) Client-Certificate and mutual authentication. ∎

This is how I solved it based on this post with some minor tweaks. This solution does not require creation of any additional classes.
SSLContext sc = SSLContext.getInstance("SSLv3");
KeyManagerFactory kmf =
KeyManagerFactory.getInstance( KeyManagerFactory.getDefaultAlgorithm() );
KeyStore ks = KeyStore.getInstance( KeyStore.getDefaultType() );
ks.load(new FileInputStream( certPath ), certPasswd.toCharArray() );
kmf.init( ks, certPasswd.toCharArray() );
sc.init( kmf.getKeyManagers(), null, null );
((BindingProvider) webservicePort).getRequestContext()
.put(
"com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory",
sc.getSocketFactory() );

I tried the following and it didn't work on my environment:
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory", getCustomSocketFactory());
But different property worked like a charm:
bindingProvider.getRequestContext().put(JAXWSProperties.SSL_SOCKET_FACTORY, getCustomSocketFactory());
The rest of the code was taken from the first reply.

By combining Radek and l0co's answers you can access the WSDL behind https:
SSLContext sc = SSLContext.getInstance("TLS");
KeyManagerFactory kmf = KeyManagerFactory
.getInstance(KeyManagerFactory.getDefaultAlgorithm());
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(getClass().getResourceAsStream(keystore),
password.toCharArray());
kmf.init(ks, password.toCharArray());
sc.init(kmf.getKeyManagers(), null, null);
HttpsURLConnection
.setDefaultSSLSocketFactory(sc.getSocketFactory());
yourService = new YourService(url); //Handshake should succeed

The above is fine (as I said in comment) unless your WSDL is accessible with https:// too.
Here is my workaround for this:
Set you SSLSocketFactory as default:
HttpsURLConnection.setDefaultSSLSocketFactory(...);
For Apache CXF which I use you need also add these lines to your config:
<http-conf:conduit name="*.http-conduit">
<http-conf:tlsClientParameters useHttpsURLConnectionDefaultSslSocketFactory="true" />
<http-conf:conduit>

You can move your proxy authentication and ssl staff to soap handler
port = new SomeService().getServicePort();
Binding binding = ((BindingProvider) port).getBinding();
binding.setHandlerChain(Collections.<Handler>singletonList(new ProxyHandler()));
This is my example, do all network ops
class ProxyHandler implements SOAPHandler<SOAPMessageContext> {
static class TrustAllHost implements HostnameVerifier {
public boolean verify(String urlHostName, SSLSession session) {
return true;
}
}
static class TrustAllCert implements X509TrustManager {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
}
}
private SSLSocketFactory socketFactory;
public SSLSocketFactory getSocketFactory() throws Exception {
// just an example
if (socketFactory == null) {
SSLContext sc = SSLContext.getInstance("SSL");
TrustManager[] trustAllCerts = new TrustManager[] { new TrustAllCert() };
sc.init(null, trustAllCerts, new java.security.SecureRandom());
socketFactory = sc.getSocketFactory();
}
return socketFactory;

Have fun!

For those trying and still not getting it to work, this did it for me with Wildfly 8, using the dynamic Dispatcher:
bindingProvider.getRequestContext().put("com.sun.xml.ws.transport.https.client.SSLSocketFactory", yourSslSocketFactory);
Note that the internal part from the Property key is gone here.

I had problems trusting a self signed certificate when setting up the trust manager. I used the SSLContexts builder of the apache httpclient to create a custom SSLSocketFactory
SSLContext sslcontext = SSLContexts.custom()
.loadKeyMaterial(keyStoreFile, "keystorePassword.toCharArray(), keyPassword.toCharArray())
.loadTrustMaterial(trustStoreFile, "password".toCharArray(), new TrustSelfSignedStrategy())
.build();
SSLSocketFactory customSslFactory = sslcontext.getSocketFactory()
bindingProvider.getRequestContext().put(JAXWSProperties.SSL_SOCKET_FACTORY, customSslFactory);
and passing in the new TrustSelfSignedStrategy() as an argument in the loadTrustMaterial method.

we faced this problem, due to a keystore clash between system integrations, so we used the following code.
private PerSecurityWS prepareConnectionPort() {
final String HOST_BUNDLE_SYMBOLIC_NAME = "wpp.ibm.dailyexchangerates";
final String PATH_TO_SLL = "ssl/<your p.12 certificate>";
final File ksFile = getFile(HOST_BUNDLE_SYMBOLIC_NAME, PATH_TO_SLL);
final String serverURI = "you url";
final KeyStore keyStore = KeyStore.getInstance("pkcs12");
keyStore.load(new FileInputStream(ksFile.getAbsolutePath()), keyStorePassword.toCharArray());
final KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
kmf.init(keyStore, keyStorePassword.toCharArray());
final HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
#Override
public boolean verify(final String hostname, final SSLSession session) {
return false;
}
};
final SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(kmf.getKeyManagers(), null, null);
final SSLSocketFactory sslSocketFactory = ctx.getSocketFactory();
final PerSecurityWS port = new PerSecurityWS_Service().getPerSecurityWSPort();
final BindingProvider bindingProvider = (BindingProvider) port;
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory",sslSocketFactory);
bindingProvider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, serverURI);
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.hostname.verifier",DO_NOT_VERIFY);
return port;
}

I tried the steps here:
http://jyotirbhandari.blogspot.com/2011/09/java-error-invalidalgorithmparameterexc.html
And, that fixed the issue. I made some minor tweaks - I set the two parameters using System.getProperty...

service = getWebServicePort(getWSDLLocation());
BindingProvider bindingProvider = (BindingProvider) service;
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory", getCustomSocketFactory());
Where the getCustomSocketFactory() returns a SSLSocketFactory created using the method mentioned above. This would only work for JAX-WS RI from the Sun-Oracle impl built into the JDK, given that the string indicating the SSLSocketFactory property is proprietary for this implementation.
At this stage, the JAX-WS service communication is secured through SSL, but if you are loading the WSDL from the same secure server () then you'll have a bootstrap problem, as the HTTPS request to gather the WSDL will not be using the same credentials than the Web Service. I worked around this problem by making the WSDL locally available (file:///...) and dynamically changing the web service endpoint: (a good discussion on why this is needed can be found in this forum)
bindingProvider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, webServiceLocation);
Now the WebService gets bootstrapped and is able to communicate through SSL with the server counterpart using a named (alias) Client-Certificate and mutual authentication. ∎

This is how I solved it based on this post with some minor tweaks. This solution does not require creation of any additional classes.
SSLContext sc = SSLContext.getInstance("SSLv3");
KeyManagerFactory kmf =
KeyManagerFactory.getInstance( KeyManagerFactory.getDefaultAlgorithm() );
KeyStore ks = KeyStore.getInstance( KeyStore.getDefaultType() );
ks.load(new FileInputStream( certPath ), certPasswd.toCharArray() );
kmf.init( ks, certPasswd.toCharArray() );
sc.init( kmf.getKeyManagers(), null, null );
((BindingProvider) webservicePort).getRequestContext()
.put(
"com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory",
sc.getSocketFactory() );

I tried the following and it didn't work on my environment:
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory", getCustomSocketFactory());
But different property worked like a charm:
bindingProvider.getRequestContext().put(JAXWSProperties.SSL_SOCKET_FACTORY, getCustomSocketFactory());
The rest of the code was taken from the first reply.

By combining Radek and l0co's answers you can access the WSDL behind https:
SSLContext sc = SSLContext.getInstance("TLS");
KeyManagerFactory kmf = KeyManagerFactory
.getInstance(KeyManagerFactory.getDefaultAlgorithm());
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(getClass().getResourceAsStream(keystore),
password.toCharArray());
kmf.init(ks, password.toCharArray());
sc.init(kmf.getKeyManagers(), null, null);
HttpsURLConnection
.setDefaultSSLSocketFactory(sc.getSocketFactory());
yourService = new YourService(url); //Handshake should succeed

The above is fine (as I said in comment) unless your WSDL is accessible with https:// too.
Here is my workaround for this:
Set you SSLSocketFactory as default:
HttpsURLConnection.setDefaultSSLSocketFactory(...);
For Apache CXF which I use you need also add these lines to your config:
<http-conf:conduit name="*.http-conduit">
<http-conf:tlsClientParameters useHttpsURLConnectionDefaultSslSocketFactory="true" />
<http-conf:conduit>

You can move your proxy authentication and ssl staff to soap handler
port = new SomeService().getServicePort();
Binding binding = ((BindingProvider) port).getBinding();
binding.setHandlerChain(Collections.<Handler>singletonList(new ProxyHandler()));
This is my example, do all network ops
class ProxyHandler implements SOAPHandler<SOAPMessageContext> {
static class TrustAllHost implements HostnameVerifier {
public boolean verify(String urlHostName, SSLSession session) {

}

public SSLSocketFactory getSocketFactory() throws Exception {
// just an example
if (socketFactory == null) {
SSLContext sc = SSLContext.getInstance("SSL");
TrustManager[] trustAllCerts = new TrustManager[] { new TrustAllCert() };
sc.init(null, trustAllCerts, new java.security.SecureRandom());
socketFactory = sc.getSocketFactory();
}
return socketFactory;

It use UrlConnection, you can use any library you want in handler.
Have fun!

For those trying and still not getting it to work, this did it for me with Wildfly 8, using the dynamic Dispatcher:
bindingProvider.getRequestContext().put("com.sun.xml.ws.transport.https.client.SSLSocketFactory", yourSslSocketFactory);
Note that the internal part from the Property key is gone here.

I had problems trusting a self signed certificate when setting up the trust manager. I used the SSLContexts builder of the apache httpclient to create a custom SSLSocketFactory
SSLContext sslcontext = SSLContexts.custom()
.loadKeyMaterial(keyStoreFile, "keystorePassword.toCharArray(), keyPassword.toCharArray())
.loadTrustMaterial(trustStoreFile, "password".toCharArray(), new TrustSelfSignedStrategy())
.build();
SSLSocketFactory customSslFactory = sslcontext.getSocketFactory()
bindingProvider.getRequestContext().put(JAXWSProperties.SSL_SOCKET_FACTORY, customSslFactory);
and passing in the new TrustSelfSignedStrategy() as an argument in the loadTrustMaterial method.

we faced this problem, due to a keystore clash between system integrations, so we used the following code.
private PerSecurityWS prepareConnectionPort() {
final String HOST_BUNDLE_SYMBOLIC_NAME = "wpp.ibm.dailyexchangerates";
final String PATH_TO_SLL = "ssl/<your p.12 certificate>";
final File ksFile = getFile(HOST_BUNDLE_SYMBOLIC_NAME, PATH_TO_SLL);
final String serverURI = "you url";
final KeyStore keyStore = KeyStore.getInstance("pkcs12");
keyStore.load(new FileInputStream(ksFile.getAbsolutePath()), keyStorePassword.toCharArray());
final KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
kmf.init(keyStore, keyStorePassword.toCharArray());
final HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
#Override
public boolean verify(final String hostname, final SSLSession session) {
return false;
}
};
final SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(kmf.getKeyManagers(), null, null);
final SSLSocketFactory sslSocketFactory = ctx.getSocketFactory();
final PerSecurityWS port = new PerSecurityWS_Service().getPerSecurityWSPort();
final BindingProvider bindingProvider = (BindingProvider) port;
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory",sslSocketFactory);
bindingProvider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, serverURI);
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.hostname.verifier",DO_NOT_VERIFY);
return port;
}

I tried the steps here:

And, that fixed the issue. I made some minor tweaks - I set the two parameters using System.getProperty...

How to handle invalid SSL certificates with Apache HttpClient? [duplicate]

This question already has answers here:
Resolving javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed Error?
(33 answers)
Closed 3 years ago.
I know, there are many different questions and so many answers about this problem... But I can't understand...
I have: ubuntu-9.10-desktop-amd64 + NetBeans6.7.1 installed "as is" from off. rep.
I need connecting to some site over the HTTPS. For this I use Apache's HttpClient.
From tutorial I read:
"Once you have JSSE correctly installed, secure HTTP communication over SSL should be as
simple as plain HTTP communication." And some example:
HttpClient httpclient = new HttpClient();
GetMethod httpget = new GetMethod("https://www.verisign.com/");
try {
httpclient.executeMethod(httpget);
System.out.println(httpget.getStatusLine());
} finally {
httpget.releaseConnection();
}
By now, I write this:
HttpClient client = new HttpClient();
HttpMethod get = new GetMethod("https://mms.nw.ru");
//get.setDoAuthentication(true);
try {
int status = client.executeMethod(get);
System.out.println(status);
BufferedInputStream is = new BufferedInputStream(get.getResponseBodyAsStream());
int r=0;byte[] buf = new byte[10];
while((r = is.read(buf)) > 0) {
System.out.write(buf,0,r);
}
} catch(Exception ex) {
ex.printStackTrace();
}
As a result I have a set of errors:

What have I to do to create simplest SSL connection?
(Probably without KeyManager and Trust manager etc. while.)

https://mms.nw.ru uses a self-signed certificate that's not in the default trust manager set. To resolve the issue, do one of the following:
Configure SSLContext with a TrustManager that accepts any certificate (see below).
Configure SSLContext with an appropriate trust store that includes your certificate.
Add the certificate for that site to the default Java trust store.
Here's a program that creates a (mostly worthless) SSL Context that accepts any certificate:
import java.net.URL;
import java.security.SecureRandom;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.KeyManager;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
public class SSLTest {
public static void main(String [] args) throws Exception {
// configure the SSLContext with a TrustManager
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(new KeyManager[0], new TrustManager[] {new DefaultTrustManager()}, new SecureRandom());
SSLContext.setDefault(ctx);
URL url = new URL("https://mms.nw.ru");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setHostnameVerifier(new HostnameVerifier() {
#Override
public boolean verify(String arg0, SSLSession arg1) {
return true;
}
});
System.out.println(conn.getResponseCode());
conn.disconnect();
}
private static class DefaultTrustManager implements X509TrustManager {
#Override
public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
#Override
public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
#Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
}
}

https://mms.nw.ru likely uses a certificate not issued by a certification authority. Consequently, you need to add the certificate to your trusted Java key store as explained in unable to find valid certification path to requested target:
When working on a client that works
with an SSL enabled server running in
https protocol, you could get error
'unable to find valid certification
path to requested target' if the
server certificate is not issued by
certification authority, but a self
signed or issued by a private CMS.
Don't panic. All you need to do is to
add the server certificate to your
trusted Java key store if your client
is written in Java. You might be
wondering how as if you can not access
the machine where the server is
installed. There is a simple program
can help you. Please download the Java
program and run
% java InstallCert _web_site_hostname_
This program opened a connection to
the specified host and started an SSL
handshake. It printed the exception
stack trace of the error that occured
and shows you the certificates used by
the server. Now it prompts you add the
certificate to your trusted KeyStore.
If you've changed your mind, enter
'q'. If you really want to add the
certificate, enter '1', or other
numbers to add other certificates,
even a CA certificate, but you usually
don't want to do that. Once you have
made your choice, the program will
display the complete certificate and
then added it to a Java KeyStore named
'jssecacerts' in the current
directory.
To use it in your program, either
configure JSSE to use it as its trust
store or copy it into your
$JAVA_HOME/jre/lib/security directory.
If you want all Java applications to
recognize the certificate as trusted
and not just JSSE, you could also
overwrite the cacerts file in that
directory.
After all that, JSSE will be able to
complete a handshake with the host,
which you can verify by running the
program again.
To get more details, you can check out
Leeland's blog No more 'unable to find
valid certification path to requested
target'

In addition to Pascal Thivent's correct answer, another way is to save the certificate from Firefox (View Certificate -> Details -> export) or openssl s_client and import it into the trust store.
You should only do this if you have a way to verify that certificate. Failing that, do it the first time you connect, it will at least give you an error if the certificate changes unexpectedly on subsequent connections.
To import it in a trust store, use:
keytool -importcert -keystore truststore.jks -file servercert.pem
By default, the default trust store should be $JAVA_HOME/jre/lib/security/cacerts and its password should be changeit, see JSSE Reference guide for details.
If you don't want to allow that certificate globally, but only for these connections, it's possible to create an SSLContext for it:
TrustManagerFactory tmf = TrustManagerFactory
.getInstance(TrustManagerFactory.getDefaultAlgorithm());
KeyStore ks = KeyStore.getInstance("JKS");
FileInputStream fis = new FileInputStream("/.../truststore.jks");
ks.load(fis, null);
// or ks.load(fis, "thepassword".toCharArray());
fis.close();
tmf.init(ks);
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, tmf.getTrustManagers(), null);
Then, you need to set it up for Apache HTTP Client 3.x by implementing one if its SecureProtocolSocketFactory to use this SSLContext. (There are examples here).
Apache HTTP Client 4.x (apart from the earliest version) has direct support for passing an SSLContext.

For Apache HttpClient 4.5+ & Java8:
SSLContext sslContext = SSLContexts.custom()
.loadTrustMaterial((chain, authType) -> true).build();
SSLConnectionSocketFactory sslConnectionSocketFactory =
new SSLConnectionSocketFactory(sslContext, new String[]
{"SSLv2Hello", "SSLv3", "TLSv1","TLSv1.1", "TLSv1.2" }, null,
NoopHostnameVerifier.INSTANCE);
CloseableHttpClient client = HttpClients.custom()
.setSSLSocketFactory(sslConnectionSocketFactory)
.build();
But if your HttpClient use a ConnectionManager for seeking connection, e.g. like this:
PoolingHttpClientConnectionManager connectionManager = new
PoolingHttpClientConnectionManager();
CloseableHttpClient client = HttpClients.custom()
.setConnectionManager(connectionManager)
.build();
The HttpClients.custom().setSSLSocketFactory(sslConnectionSocketFactory) has no effect, the problem is not resolved.
Because that the HttpClient use the specified connectionManager for seeking connection and the specified connectionManager haven't register our customized SSLConnectionSocketFactory. To resolve this, should register the The customized SSLConnectionSocketFactory in the connectionManager. The correct code should like this:
PoolingHttpClientConnectionManager connectionManager = new
PoolingHttpClientConnectionManager(RegistryBuilder.
<ConnectionSocketFactory>create()
.register("http",PlainConnectionSocketFactory.getSocketFactory())
.register("https", sslConnectionSocketFactory).build());
CloseableHttpClient client = HttpClients.custom()
.setConnectionManager(connectionManager)
.build();

The Apache HttpClient 4.5 way:
org.apache.http.ssl.SSLContextBuilder sslContextBuilder = SSLContextBuilder.create();
sslContextBuilder.loadTrustMaterial(new org.apache.http.conn.ssl.TrustSelfSignedStrategy());
SSLContext sslContext = sslContextBuilder.build();
org.apache.http.conn.ssl.SSLConnectionSocketFactory sslSocketFactory =
new SSLConnectionSocketFactory(sslContext, new org.apache.http.conn.ssl.DefaultHostnameVerifier());
HttpClientBuilder httpClientBuilder = HttpClients.custom().setSSLSocketFactory(sslSocketFactory);
httpClient = httpClientBuilder.build();
NOTE: org.apache.http.conn.ssl.SSLContextBuilder is deprecated and org.apache.http.ssl.SSLContextBuilder is the new one (notice conn missing from the latter's package name).

From http://hc.apache.org/httpclient-3.x/sslguide.html:
Protocol.registerProtocol("https",
new Protocol("https", new MySSLSocketFactory(), 443));
HttpClient httpclient = new HttpClient();
GetMethod httpget = new GetMethod("https://www.whatever.com/");
try {
httpclient.executeMethod(httpget);
System.out.println(httpget.getStatusLine());
} finally {
httpget.releaseConnection();
}
Where MySSLSocketFactory example can be found here. It references a TrustManager, which you can modify to trust everything (although you must consider this!)

want to paste the answer here:
in Apache HttpClient 4.5.5
How to handle invalid SSL certificate with Apache client 4.5.5?
HttpClient httpClient = HttpClients
.custom()
.setSSLContext(new SSLContextBuilder().loadTrustMaterial(null, TrustAllStrategy.INSTANCE).build())
.setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
.build();

Once you have a Java Cert Store (by using the great InstallCert class created above), you can get java to use it by passing the "javax.net.ssl.trustStore" param at java startup.
Ex:
java -Djavax.net.ssl.trustStore=/path/to/jssecacerts MyClassName

Another issue you may run into with self signed test certs is this:
java.io.IOException: HTTPS hostname wrong: should be ...
This error occurs when you are trying to access a HTTPS url. You might have already installed the server certificate to your JRE's keystore. But this error means that the name of the server certificate does not match with the actual domain name of the server that is mentioned in the URL. This normally happens when you are using a non CA issued certificate.
This example shows how to write a HttpsURLConnection DefaultHostnameVerifier that ignore the certificates server name:
http://www.java-samples.com/showtutorial.php?tutorialid=211

EasySSLProtocolSocketFactory was giving me problems so I ended up implementing my own ProtocolSocketFactory.
First you need to register it:
Protocol.registerProtocol("https", new Protocol("https", new TrustAllSSLSocketFactory(), 443));
HttpClient client = new HttpClient();
...
Then implement ProtocolSocketFactory:
class TrustAllSSLSocketFactory implements ProtocolSocketFactory {
public static final TrustManager[] TRUST_ALL_CERTS = new TrustManager[]{
new X509TrustManager() {
public void checkClientTrusted(final X509Certificate[] certs, final String authType) {
}
public void checkServerTrusted(final X509Certificate[] certs, final String authType) {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
}
};
private TrustManager[] getTrustManager() {
return TRUST_ALL_CERTS;
}
public Socket createSocket(final String host, final int port, final InetAddress clientHost,
final int clientPort) throws IOException {
return getSocketFactory().createSocket(host, port, clientHost, clientPort);
}
#Override
public Socket createSocket(final String host, final int port, final InetAddress localAddress,
final int localPort, final HttpConnectionParams params) throws IOException {
return createSocket(host, port);
}
public Socket createSocket(final String host, final int port) throws IOException {
return getSocketFactory().createSocket(host, port);
}
private SocketFactory getSocketFactory() throws UnknownHostException {
TrustManager[] trustAllCerts = getTrustManager();
try {
SSLContext context = SSLContext.getInstance("SSL");
context.init(null, trustAllCerts, new SecureRandom());
final SSLSocketFactory socketFactory = context.getSocketFactory();
HttpsURLConnection.setDefaultSSLSocketFactory(socketFactory);
return socketFactory;
} catch (NoSuchAlgorithmException | KeyManagementException exception) {
throw new UnknownHostException(exception.getMessage());
}
}
}
Note: This is with HttpClient 3.1 and Java 8

For a way to easily add hosts you trust at runtime without throwing out all checks, try the code here: http://code.google.com/p/self-signed-cert-trust-manager/.

I happened to face the same issue, all of a sudden all my imports were missing. I tried deleting all the contents in my .m2 folder. And trying to re-import everything , but still nothing worked.
Finally what I did was opened the website for which the IDE was complaining that it couldn't download in my browser. And saw the certificate it was using, and saw in my
$ keytool -v -list PATH_TO_JAVA_KEYSTORE
Path to my keystore was /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/security/cacerts
that particular certificate was not there.
So all you have to do is put the certificate into the JAVA JVM keystore again.
It can be done using the below command.
$ keytool -import -alias ANY_NAME_YOU_WANT_TO_GIVE -file PATH_TO_YOUR_CERTIFICATE -keystore PATH_OF_JAVA_KEYSTORE
If it asks for password, try the default password 'changeit'
If you get permission error when running the above command.
In windows open it in administration mode.
In mac and unix use sudo.
After you have successfully added the key,
You can view it using :
$ keytool -v -list /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/security/cacerts
You can view just the SHA-1 using teh command
$ keytool -list /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/security/cacerts

This link explains the requirement you have step by step. If You are not really concerned which certificate you can proceed with the process in below link.
Note You might want to double check what you are doing since, this is a unsafe operation.

Using the InstallCert to generate the jssecacerts file and do
-Djavax.net.ssl.trustStore=/path/to/jssecacerts worked great.

I'm useing httpclient 3.1.X ,and this works for me
try {
SSLContext sslContext = SSLContext.getInstance("TLS");

};

For HttpClient, we can do this :
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(new KeyManager[0], new TrustManager[] {new DefaultTrustManager()}, new SecureRandom());
SSLContext.setDefault(ctx);
String uri = new StringBuilder("url").toString();
HostnameVerifier hostnameVerifier = new HostnameVerifier() {
#Override
public boolean verify(String arg0, SSLSession arg1) {
return true;
}
};
HttpClient client = HttpClientBuilder.create().setSSLContext(ctx)
.setSSLHostnameVerifier(hostnameVerifier).build()

follow the instruction given below for Java 1.7, to create an SSL certificate using InstallCert.java program file.
https://github.com/escline/InstallCert
you must restart the tomcat

Used the following along with DefaultTrustManager and it worked in httpclient like charm. Thanks a ton!! #Kevin and every other contributor
SSLContext ctx = null;
SSLConnectionSocketFactory sslsf = null;
try {
ctx = SSLContext.getInstance("TLS");
ctx.init(new KeyManager[0], new TrustManager[] {new DefaultTrustManager()}, new SecureRandom());
SSLContext.setDefault(ctx);
sslsf = new SSLConnectionSocketFactory(
ctx,
new String[] { "TLSv1" },
null,
SSLConnectionSocketFactory.getDefaultHostnameVerifier());
} catch (Exception e) {
e.printStackTrace();
}
CloseableHttpClient client = HttpClients.custom()
.setSSLSocketFactory(sslsf)
.build();
