TITLE: Losing passwords like a boss

 

ABSTRACT: Modern encryption techniques are used all over the place to protect your communications and data. These techniques are subtle, and even small changes to an algorithm can render it totally freaking useless. We'll talk about these techniques in the context of block ciphers, and find out how a large and (in)famous software company totally screwed it up and lost people's passwords because of a poor implementation. We'll learn the exact details of some block cipher attacks and, time permitting, practice breaking some other systems.
