Nice Page!
But, in my opinion, it would be nice to know "why". Sure, i can digg into it, spend a day to understand or can use Google to find the answer; But it would be awesome if they will provide that information on the pages to the algorithms.
I.e the SHA 256 Page: I really like it. But if i'm new in this field, and don't even know about it a simple Wikipedia link would be enough to give me an "introduction" to the Algorithm. And, without it: It stays nice :)
