The Linux Foundation has been working on a free SSL certificate generating tool for a while with the assistance of Cisco, Akamai, the EFF, Mozilla, and others.  The key about this is that it is a legitimate SSL certificate generated by a trusted root CA, all for free!

The install process was ridiculously painless and took me less than about 15 minutes from start to finish.  I can’t recommend this highly enough.  It is imperative that people learn about encryption and cryptography and protect their sites and their content with encryption.
