[java] Is there a java setting for disabling certificate validation?

I received this error while trying to start up an application:

Sun.security.validator.ValidatorException: PKIX path validation failed: 
java.security.cert.CertPathValidatorException:  java.net.UnknownHostException:oscp.thawte.com

The application is behind a closed network and won't ever be able to get to oscp.thawte.com. Is there a java setting that can disable this?

It is very simple .In my opinion it is the best way for everyone

       Unirest.config().verifySsl(false);
       HttpResponse<String> response = null;
       try {
           Gson gson = new Gson();
           response = Unirest.post("your_api_url")
                   .header("Authorization", "Basic " + "authkey")
                   .header("Content-Type", "application/json")
                   .body("request_body")
                   .asString();
           System.out.println("------RESPONSE -------"+ gson.toJson(response.getBody()));
       } catch (Exception e) {
           System.out.println("------RESPONSE ERROR--");
           e.printStackTrace();
       }
   }

In Axis webservice and if you have to disable the certificate checking then use below code:

AxisProperties.setProperty("axis.socketSecureFactory","org.apache.axis.components.net.SunFakeTrustSocketFactory");

Not exactly a setting but you can override the default TrustManager and HostnameVerifier to accept anything. Not a safe approach but in your situation, it can be acceptable.

In addition to the answers above. You can do it programmatically by implementing the TrustManager:

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);

However this is not a good practice for production.

This example on How to disable SSL certificat validation in Java contains a utility class you can copy in your project.

Use cli utility keytool from java software distribution for import (and trust!) needed certificates

Sample:

1. From cli change dir to jre\bin

2. Check keystore (file found in jre\bin directory)
   keytool -list -keystore ..\lib\security\cacerts
   Enter keystore password: changeit

3. Download and save all certificates chain from needed server.

4. Add certificates (before need to remove "read-only" attribute on file "..\lib\security\cacerts") keytool -alias REPLACE_TO_ANY_UNIQ_NAME -import -keystore ..\lib\security\cacerts -file "r:\root.crt"

accidentally I found such a simple tip. Other solutions require the use of InstallCert.Java and JDK

On my Mac that I'm sure I'm not going to allow java anyplace other than a specific site, I was able to use Preferences->Java to bring up the Java control panel and turned the checking off. If DLink ever fixes their certificate, I'll turn it back on.
