Speaker: Daniel Crowley Application Security Consultant, Trustwave - SpiderLabs

Cryptography is often used to secure data, but few people have a solid understanding of cryptography. It is often said that if you are not strictly a cryptographer, you will get cryptography wrong. For that matter, if you ARE a cryptographer, it is still easy to make mistakes. The algorithms might be peer reviewed and unbroken for 15 years, but if you use them incorrectly, they might leak information. Cryptographic oracles are systems which take user-controlled input and leak part or all of the output, generally leading to an attacker being able to defeat the cryptography, in part of in whole. In this talk, methods for finding and exploiting encryption, decryption, and padding oracles with minimal cryptographic knowledge will be discussed.
