I tried this back in April: https://news.ycombinator.com/item?id=7616270 https://news.ycombinator.com/item?id=7616270 I liked the Matasano Crypto Challenges, but this was less informative. It's a list of tasks, not a tutorial. There weren't pointers to resources, either. There were 20 tasks then, btw.
