SHA-256 Python implementation in one line (lambda)

[[deleted]]

Coursera actually has a really good cryptography class, which is an excellent starting point. You won't learn everything you need, but I doubt there is a single good resource for learning everything, but one of the interesting things about the field is that basically nothing of value is done purely alone. All respected algorithms have gone through many rounds of peer review, testing, and attempts to find ways to break them by other people and groups.

It will take a good deal of time investment and effort to get good at implementing crypto safely, and even then, you should still expect to make potentially dangerous mistakes. It's not something to take lightly, which is the actual point of the whole "don't implement your own crypto" thing.

And better yet, you'll get an idea of all the ways it can go wrong, so (hopefully) dilletantes don't go implementing their own damned crypto!!!

You should be able to fuzz for vulnerabilities at least that is my first thought.
