Derick Rethans has already posted the slides from his talk at the PHP Quebec Conference 2005 - both here: Encryption and Data Security and the Performance Workshop.

The second session I gave on the PHP Quebec conference was on encrypting and data security. Slides are again here. On my last slide I put a puzzle, which would give the first person that figured it out a copy of my book. I'll repeat the puzzle here (and no Jason, you can not compete again ;-)).

Who else figures it out?

(The book is Prentice Hall's PHP 5 Power Programming, a staple of any book collection...)
