This is a command-line tool to test server support for TLS protocols and ciphers. If you forgot to, that’s probably why the SSL/TLS handshake failed. You are looking for this at the bottom of the output. To facilitate this, a copy of the server’s public SSL certificate is installed in the client keystore as well. To connect to an end-point, just create a new WebSocket instance, providing the new object with a URL that represents the end-point to which you wish to connect, as shown in the following example.
