Java Question

Is it possible to get Java to ignore the "trust store" and just accept whatever SSL certificate it gets?

I am trying to write an SSL client that sends mail using the javax.mail API. The problem I am having is that the server request that I use SSL, but the server is also configured with a non-standard SSL certificate. The web pages I have found say that I need to install the certificate into the trust store. I don't want to do that (I don't have the necessary permissions.)

  1. Is there a way to get Java to just ignore the certificate error and accept it?

  2. Failing that, is there a way to have the trust store be local for my program, and not installed for the whole JVM?

You need to create a fake TrustManager that accepts all certificates, and register it as a manager. Something like this:

public class MyManager implements com.sun.net.ssl.X509TrustManager {
  public boolean isClientTrusted(X509Certificate[] chain) { return true; }
  public boolean isHostTrusted(X509Certificate[] chain) { return true; }

com.sun.net.ssl.TrustManager[] managers =
  new com.sun.net.ssl.TrustManager[] {new MyManager()};

       .init(null, managers, new SecureRandom());
