[Htmlunit-user] Accessing secure websites with untrusted certificates

[Ramachandran, N. <ne...@am...>]

Hi,

I want to accept all the certificates irrespective of whether it is =
trusted or not. I tried the following code snippet but, still I am =
getting CertificateException. Is there a solution for this?

            TrustManager[] trustAllCerts =3D new TrustManager[]{

                new X509TrustManager() {

                    public java.security.cert.X509Certificate[] =
getAcceptedIssuers() {

                        return null;

                    }

                    public void checkClientTrusted(

                        java.security.cert.X509Certificate[] certs, =
String authType) {

                    }

                    public void checkServerTrusted(

                        java.security.cert.X509Certificate[] certs, =
String authType) {

                    }

                }

            };

               =20

            // Install the all-trusting trust manager

            try {

                SSLContext sc =3D SSLContext.getInstance("SSL");

                sc.init(null, trustAllCerts, new =
java.security.SecureRandom());

                =
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

            } catch (Exception e) {

            }           =20
