It's feature complete, I've done a lot of unit tests, have about 90% code coverage, run various freely available static analysis, built it on linux and windows, but what I've really lacked is another person to actually look at the code.
It's easy to make crypto mistakes, even when you know the common mistakes yourself. So I'd appreciate any comments, code reviews, thoughts, and issues.
Thanks!
