I've been working on a C# implementation of Keyczar or months now. You can find it on github.<p>http://jbtule.github.com/keyczar-dotnet/<p>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.<p>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.<p>Thanks!
