I'm using Node.js's elliptic library to do some signing on my app, but there is some chance I'll migrate it to another language. That library is kinda big and not easy to port, so, I wonder, is there a reference, siple implementation of ECDSA algorithms (key generation, signing and recovery) anywhere?

I wrote the Ruby ECDSA gem and I would say the code is pretty simple. That was one of my main goals.
