Lunch Hour Crypto Challenge

Being an inquisitive geek, I have an interest in codes, cryptography and cracking (from a purely educational point of view of course). We’ve already featured some good sites for learning the basics (like CyberArmy or Hackquest) but there’s a new competition out there on the thawte site. It’s probably a bit hard for most of you guys (and me!) but why not try the Lunch Hour Challenge. Of course, if you can do it in your lunch hour then I’ll be very impressed!
