How to disable SSL certificat validation in Java

This fix will disable the SSL certificate validation. It is not recommanded in a production environment. A recommanded approach is to install the needed certificates on the JVM.

Create the following class:

import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;


public class SSLFix {
 
 public static void execute(){
  TrustManager[] trustAllCerts = new TrustManager[] {
        new X509TrustManager() {
          public java.security.cert.X509Certificate[] getAcceptedIssuers() {
           return null;
          }
          @Override
          public void checkClientTrusted(X509Certificate[] arg0, String arg1)
           throws CertificateException {}
 
          @Override
          public void checkServerTrusted(X509Certificate[] arg0, String arg1)
            throws CertificateException {}

          }
     };

  SSLContext sc=null;
  try {
   sc = SSLContext.getInstance("SSL");
  } catch (NoSuchAlgorithmException e) {
   e.printStackTrace();
  }
  try {
   sc.init(null, trustAllCerts, new java.security.SecureRandom());
  } catch (KeyManagementException e) {
   e.printStackTrace();
  }
  HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

  // Create all-trusting host name verifier
  HostnameVerifier validHosts = new HostnameVerifier() {
  @Override
  public boolean verify(String arg0, SSLSession arg1) {
   return true;
  }
  };
  // All hosts will be valid
  HttpsURLConnection.setDefaultHostnameVerifier(validHosts);
 }

}

Now whenever you want to create a SSL connection, add the following line just before the connection:

SSLFix.execute();
