Client side SSL with Spring-WS - ssl

I'm trying to use mutual authentication (certs on both client and server) but I'm then getting this error:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Then I found this class which I tried to use as a messageSender:
HttpsUrlConnectionMessageSender
But I can't figure out how to setup keystores and truststores which I have configure with javax.net.ssl properties.
If possible I would like to do this setup in spring xml files so it can dynamically configured.

Checkout here.
You just have to generate a certificate and place in JRE library path and no need to use any message sender.
http://www.mkyong.com/webservices/jax-ws/suncertpathbuilderexception-unable-to-find-valid-certification-path-to-requested-target/
Certificate generator https://code.google.com/p/java-use-examples/source/browse/trunk/src/com/aw/ad/util/InstallCert.java
Then if you face this exception java.security.cert.CertificateException
Then just override the verifier
static {
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
// HOST_ADDRESS = Endpoint host address
if (hostname.equals(HOST_ADDRESS))
return true;
return false;
}
});
}

Host name check in Custom Trust Manager

We have a java client that allows both secure and non-secure connections to LDAP hosts.
It comes as part of a software suite which
has its own server component.
We are good with non-secure connections but need to switch to secure only.
The trusted public certificates are maintained (root+intermediate+host are copy pasted into one PEM file) in a
central location with the server component external to the clients.
The custom trust manager downloads the externally held trusted certificates on demand
and builds the trusted certificate chain. This way, I guess, it avoids pre-saving the trusted certicate chain in each client.
Our LDAP hosts are load balanced and that setup has not gone well with the trust manager. When we investigated, we found two questionable lines
in the code.
An environment variable to by-pass the host name verification.
if ("T".equals(System.getenv("IGNORE_HOSTNAME_CHECK"))) return true;
It seems like doing something similar to below which I have seen elsewhere.
HostnameVerifier allHostsValid = new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
};
HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
Host name check relies on CN value of subject alone.
if (this.tgtHostname.equalsIgnoreCase(leafCn)) return true;
I have skimmed through some RFCs related to TLS and have come across SNI, SAN:DNSName and MITM warnings
but my rudimentary knowledge is not enough to make a case one way or the other.
Any advice on improvements (or against the use of it altogether) around commented out lines labelled H1 and H2 will be greatly valued.
I intend to pass them on to the right entity later.
The cut-down version of checkServerTrusted() of the custom trust manager is pasted below.
public void checkServerTrusted(X509Certificate[] certsRcvdFromTgt, String authType) throws CertificateException
{
// Some stuff
// Verify that the last certificate in the chain corresponds to the tgt server we want to access.
checkLastCertificate(certsRcvdFromTgt[certsRcvdFromTgt.length - 1]);
// Some more stuff
}
private boolean checkLastCertificate(X509Certificate leafCert) throws CertificateException
{
// need some advice here ... (H1)
if ("T".equals(System.getenv("IGNORE_HOSTNAME_CHECK"))) return true;
try
{
String leafCn = null;
X500Principal subject = leafCert.getSubjectX500Principal();
String dn = subject.getName();
LdapName ldapDN = new LdapName(dn);
for (Rdn rdn : ldapDN.getRdns())
{
if (rdn.getType().equalsIgnoreCase("cn"))
{
leafCn = rdn.getValue().toString();
break;
}
}
// need some advice here ... (H2)
if (this.tgtHostname.equalsIgnoreCase(leafCn)) return true;
}
catch (InvalidNameException e){/*error handling*/}
throw new CertificateException("Failed to verify that the last certificate in the chain is for target " + this.tgtHostname);
}

Apache camel SSL connection to restful service

I am busy with a project where I have to do a GET on an exposed rest service using specific certificates. I am using the apache camel framework with the https4 component. I created a keystore and tested it using soapUI and it connected successfully, but I am however unable to connect through my project.
I used the following page as reference: http://camel.apache.org/http4.html
I set up the SSL for the HTTP Client through the following configuration:
<spring:sslContextParameters id="sslContextParameters">
<spring:keyManagers keyPassword="xxxx">
<spring:keyStore resource="classpath:certificates/keystore.jks" password="xxxx"/>
</spring:keyManagers>
</spring:sslContextParameters>
<setHeader headerName="CamelHttpMethod">
<simple>GET</simple>
</setHeader>
My endpoint is configured as:
<to uri="https4://endpointUrl:9007/v1/{id}?sslContextParametersRef=sslContextParameters"/>
The stacktrace I am receiving:

Any help would be much appreciated !
Just same: I followed documented instructions and got too stuck on "PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target". There's a quick fix, but if you want to link the configuration to the client HTTP session at stake, it becomes a complex set-up.
Method 1:
Doc pages, forums, and this other article would tell you that setting JVM launch options "-Djavax.net.ssl.trustStore=myKeystore.jks -Djavax.net.ssl.trustStorePassword=mystorepass" do solve the issue, provided the remote parties' certificates (self signed, or signed by a CA but then with all the full certificate chain) were all fetched as Trusted certificates in the supplied keystore. Fact is, HTTP4 is based on JSSE, and these java launch options do configure the stack JVM-wide.
As an alternative, you can also fetch peers' certificates (complete chains) in the default JVM keystore jre\lib\security\cacerts (initial password: "changeit") and thus not even need JVM options.
If you have a few outgoing client connections and few peer certificates, this is the simplest way.
Method 2:
In our context, with above 100 remote parties, each requiring certificate updates every 2 years in average, that method implies a JVM reboot on an updated keystore about every week. Our highly available gateway is no longer highly available. So I searched a dynamic/per-connexion/programmatic way.
Below is a simplified excerpt of code from a CAMEL Processor that we use to remotely connect as REST or plain-vanilla HTTP client, with or without SSL/TLS, and with or without client-side certificate (i.e. 2-way SSL/TLS versus 1-way SSL/TLS), as well as combine HTTP Basic Auth as required by peers.
For various reasons the now old CAMEL version 2.16.3 is still used in our context. I have not tested yet newer versions. I suspect no changes given the libraries at stake under the Apache CAMEL layer.
I have added in the code below many comments detailling variant API's to the same effect. So you have clues below to further simplify the code or try alternatives with newer HTTP4 versions. As is, the code works with 2.16, as a CAMEL Processor bean within a Spring application context that contains the entire CAMEL route definition in DSL.
In our context we use java code for configuring entirely dynamic SSL/TLS outbound connexions per session. You should have no difficulties freezing part of the configuration that we set below dynamically via java, into the CAMEL XML DSL as suitable to your context.

Hope this helps. I spent many hours trying to get it working (although I know well about SSL/TLS principles, security, X509, etc) ... This code is far from my taste for clean and lean java code. In addition I assumed that you do know how to build a keystore, supply all needed certificate chains, define a CAMEL route, etc. As such, it works with Camel 2.16 within a Spring Application Context, and has no other pretention than providing clues that would save you hours.

Apache HttpClient SelfSigned certificates

A self signed certificate is one that is not signed by a Certificate Authority(CA). JAVA stores the certificates of most of the CA (here jre/lib/security/cacerts) and so if you want to connect to an https site with certificate signed by a CA there is no special code for it. (the same code for http call would work)
So basically
CloseableHttpClient httpclient = HttpClients.createDefault();
HttpGet httpGet = new HttpGet(https_url);
httpclient.execute(httpGet)
But if we have a self signed certificate then we would need to configure the client and make it work. Otherwise we would see
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
javax.net.ssl.SSLPeerUnverifiedException: Host name 'localhost' does not match the certificate subject provided by the peer ...
How to configure http client for this case?
httpclient 4.x
Approach 1
Configure the TrustStrore through debug options
-Djavax.net.ssl.trustStore=/Users/amodpandey/.keystore
Java is able to read the truststore even without passing the password (password of the truststore)
But even after this you might face
javax.net.ssl.SSLPeerUnverifiedException: Host name 'localhost' does not match the certificate subject provided by the peer ...
CloseableHttpClient httpClient =
HttpClientBuilder.create()
.setSSLHostnameVerifier(new HostnameVerifier() {
#Override
public boolean verify(String arg0, SSLSession arg1) {
return true;
}
})
.build();
And it works..
Approach 2
Put it all in the code
CloseableHttpClient httpClient =
HttpClientBuilder.create()
.setSslcontext(SSLContexts.custom().loadTrustMaterial(new File(Thread.currentThread().getContextClassLoader().getResource("keystore").getFile())).build())
.setSSLHostnameVerifier(new HostnameVerifier() {
#Override
public boolean verify(String arg0, SSLSession arg1) {
return true;
}
})
.build();
Approach 3
While using a connection manager
The setSslcontext and setSSLHostnameVerifier are ignore when using
.setConnectionManager(connectionManager)
So connection manager should be configured
Files.copy(ClassLoader.getSystemResourceAsStream("keystore"), Paths.get(URI.create("file:/tmp/keystore")),
StandardCopyOption.REPLACE_EXISTING);
Registry<ConnectionSocketFactory> socketFactoryRegistry =
RegistryBuilder
.<ConnectionSocketFactory>create()
.register(
"https",
new SSLConnectionSocketFactory(SSLContextBuilder.create()
.loadTrustMaterial(new File("/tmp/keystore")).build(),
new HostnameVerifier() {
#Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
})).register("http", PlainConnectionSocketFactory.INSTANCE).build();
PoolingHttpClientConnectionManager connectionManager =
new PoolingHttpClientConnectionManager(socketFactoryRegistry);
CloseableHttpClient httpClient =
HttpClientBuilder.create()
.setConnectionManager(connectionManager)
.build();
Note
-Djavax.net.debug=all debug option is very helpful to see the certificates being used
The SSLContext uses File and if we plan to package the certificate with the code in a Jar then we would need to create a file to pass it to the File object (it does not for files inside the jar)
Files.copy(ClassLoader.getSystemResourceAsStream("keystore"),Paths.get(URI.create("file:/tmp/utskeystore")),StandardCopyOption.REPLACE_EXISTING)

Selenium SSL Handshake Problem

While attempting to access a test portal, I'm encountering the following problem while using the selenium.start("captureNetworkTraffic=true"); mode.
HTTP ERROR: 400
Could not proxy https://myurl.com
java.lang.RuntimeException: Couldn't establish SSL handshake. Try using trustAllSSLCertificates.
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
RequestURI=/auth/login
Note that this happens only in the captureNetworkTrafficMode. A simple selenium.start(); works with no problem at all.
Here's the access code -
RemoteControlConfiguration settings = new RemoteControlConfiguration();
File f = new File("C:\\selenium-profile");
BrowserConfigurationOptions bco = new BrowserConfigurationOptions();
bco.setCommandLineFlags("-trustAllSSLCertificates");
bco.setCommandLineFlags("-disable-web-security");
bco.setCommandLineFlags("-avoidProxy");
settings.setFirefoxProfileTemplate(f);
settings.setReuseBrowserSessions(true);
settings.setSingleWindow(true);
SeleniumServer seleniumserver=new SeleniumServer(settings);
seleniumserver.boot();
seleniumserver.start();
selenium = new DefaultSelenium("localhost",4444,"*chrome","http://myurl.com") {
public void open(String url) {
commandProcessor.doCommand("open", new String[] {url,"true"});
}
};
selenium.start("captureNetworkTraffic=true");
selenium.open("/");
This problem seems to have been beaten to death, but I still haven't come across a convincing solution...Most recommend the creation of a custom FF profile, but this doesn't work.
It boiled down to an additional browser setting to trust all SSL certificates:
settings.setTrustAllSSLCertificates(true);

I am using WCF for the client to access service. I am trying to access the endpoint with TLS (https). I have certificates with both private and public keys.
If I have the end point of the service to have the host name same as the certificate name ("Issued To"), then i am able to access the service from the client.
If the names of the "issued to" and end point domain name are different i get the error "Could not establish trust relationship for the SSL/TLS secure channel with authority". I have added the certificates to "Trusted Root", "Personal" and "trusted People". In my service i have used "PeerOrChainTrust".
Please let me know if anybody has any idea on this
In that case, you need to define the trust policy for the server on client side,
Call SetCertPolicy once before you make any call to the services.
using System.Net;
using System.Security.Cryptography.X509Certificates;
public static void SetCertPolicy()
{
ServicePointManager.ServerCertificateValidationCallback += RemoteCertValidate;
}
private static bool RemoteCertValidate( object sender, X509Certificate cert, X509Chain chain,
SslPolicyErrors error )
{
// trust any cert!!!
return true;
}
