“This article explains how you can set up SSL vhosts under nginx
on Ubuntu 11.04 and Debian Squeeze so that you can access the vhost
over HTTPS (port 443). SSL is short for Secure Sockets Layer and is
a cryptographic protocol that provides security for communications
over networks by encrypting segments of network connections at the
transport layer end-to-end. In addition to that I will show how to
make use of SNI (Server Name Indication) to allow multiple SSL
vhosts per IP address. “
