Ever wondered how to provide your end-users with end-to-end (does that count towards my pun quota for the day?) encryption without paying a cent?

https://www.startssl.com - All you need is an email address (i.e. webmaster@hacktalk.net) and 20 minutes of playing around with Apache/nginx/lighttpd to install it.

https://calomel.org/ - Great website for learning the ins-and-outs of configuration

Disclaimer: If HTTPS was part of HackTalk before the server move and it just hasn't been re-enabled, feel free to discard this.

WoT bitched about StartSSL? Gay. Did you get the certificate order right? https://sslcheck.globalsign.com/en_US

If you need help, I can mail you a slightly redacted copy of my nginx config for a project at work (with unused certs & irrelevant private keys) that uses StartSSL. For comparison and whatnot.
