java.lang.Object

js.lang.DefaultTrustManager

All Implemented Interfaces:

TrustManager, X509TrustManager

public class DefaultTrustManager
extends Object
implements X509TrustManager

Default trust manager accept all client and server certificates. It is primarily used to initialize a SSL context for secure HTTP connection.

In sample below secure context is initialized before creating HTTPS connection. It uses default trust manager to accept server certificate.

 SSLContext sslContext = SSLContext.getInstance("TLS");
 sslContext.init(new KeyManager[0], new TrustManager[]
 {
   new DefaultTrustManager()
 }, new SecureRandom());
 SSLContext.setDefault(sslContext);
 ...
 HttpsURLConnection connection = (HttpsURLConnection)url.openConnection();
