I can see the amusement I can derive from Stupid is going to be endless. If somewhat stupid.
More seriously, Ben Clifford wrote a Haskell plugin for Stupid. So, with his permission, I have added it to the source. I’ve also created a Google Code site for it – sadly someone already has stupid.googlecode.com, so you’ll find it at stupid-crypto.googlecode.com.
Ben also added a lot of test cases, which I haven’t yet pulled in because I want to move them into their own directory, but they may be there by the time you check the code out.
I still haven’t got around to testing the SHA-256 implementation, either. One day! Oh, and it seems the Haskell breaks, which may well be my fault. But I don’t really understand Haskell, so I might find it hard to fix.
