How can I edit the list of cipher suite in Java using Bouncy Castle

Question

The following code lists the supported cipher suites by Java SE 8:

import java.io.IOException;
import java.net.UnknownHostException;
import java.util.Arrays;         


        

Answer 1

You can't edit the cipher suites directly on factory.

However you can choose what exact ciphers to support (from the available) on the SSLSocket

SSLSocketFactory factory = HttpsURLConnection.getDefaultSSLSocketFactory();
String[] cipherSuites = factory.getSupportedCipherSuites();
SSLSocket sslSocket = (SSLSocket) factory.createSocket();

// Choose the exact ciphers you need from the available
String[] filteredCipherSuites = cipherSuites; 

sslSocket.setEnabledCipherSuites(filteredCipherSuites);
