Another year at New York PHP is almost past, but it wouldn't be complete without the ever important topic of security. Join New York PHP and seasoned web architect and author Nick Galbreath as he explains how cryptography can make your PHP application stronger and tamper proof. Don't be a turkey and let your URLs get compromised - gobble gobble.

Tamper Proof URLs: An Introduction to Cryptography.

Using a standard cryptographic technique we can construct "tamper proof URLs". By preventing user modifications to a URL, one can help prevent cross-site scripting, parameter modification and parameter scanning. In addition we can make URLs that expire and can allow "single sign on" between two websites or applications.

This talk will provide a introduction to cryptography, the PHP modules that provide cryptographic services, and sample implementation of the tamper proof URL technique.

Nick Galbreath have been working on high performance servers and web security at various high profile startups since 1994 (most recently Right Media). He holds a Master degree of Mathematics from Boston University, and published a book on cryptography. He currently lives in the Lower East Side.
