Learn about the inner workings of cryptographic primitives and protocols and how to apply this knowledge in real-world applications. A free textbook covering the material in the course is available at http://cryptobook.us. This course will launch once the textbook is complete.
This is a famous course, but not for its quality, but for it being vaporware. It will always start next autumn. It will probably handle zero knowledge proofs first, because it has contained zero knowledge for years on end now.
