We are using the standard OpenVPN SSL VPN connections. The connection behaves very similar to a regular https connection that your web browser might make. </para><section><title>Getting started</title><section><title>Request a key</title><para>The connection uses a combination of a symmetric cipher and public key cryptography. That is why we need to generate a pair of keys for you. You can request a key by sending an e-mail to your local sysadmin (il-action@cs or akrevl@cs). </para></section><section><title>Copy the key</title><para>Once you get a reply from your sysadmin you can copy the key via SSH from the whale.stanford.edu server. </para><section><title>Windows users</title><para>You will need a program that can transfer files via the SSH protocol.
