A useful introduction to cryptography and cryptanalysis and a good place to start the study of the subject and get familiar with terms and concepts useful to practice.
(b) The Cryptology Independent Study Project
“This project is intended to fill a void in the area of cryptologic study and research. There are many universities with programs in computer science and mathematics that fail to address the area of cryptology. This is, perhaps, not the most surprising trend, but it does leave those of us who are genuinely interesting in the area with nowhere to turn. Our hopes are that this project will help fill this void, and that we can grow a community based on our common interest and love for making and breaking codes.”
