I finally posted my slides for "Tamperproof URLS and PHP" from the NYPHP talk on 27-Nov-2007 at http://modp.com/slides/securestring/. In addition the source code and unit test are posted. This is a temporary spot until code.google.com bumps up my resources and then it will go into SVN.
Thank you all for coming. Based on the questions and feedback, I have completely revamped the slides and added a lot more examples. Enjoy! --nickg

Does anyone have audio or video from the presentation?
