Anyone done these before? Looks like fun, just sent the request e-mail. I'll try to report back!
We've built a collection of 48 exercises that demonstrate attacks on real-world crypto.
This is a different way to learn about crypto than taking a class or reading a book. We give you problems to solve. They're derived from weaknesses in real-world systems and modern cryptographic constructions. We give you enough info to learn about the underlying crypto concepts yourself. When you're finished, you'll not only have learned a good deal about how cryptosystems are built, but you'll also understand how they're attacked.
