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.
How does this work?
