I have worked with encryption quite extensively, it is one of my favorite topics, and I feel I have a lot of experience with GNUPG, RSA, and DSA algorithms. I can take a few hours and learn how to work with any other algorithm you need though.
I don't have a lot of experience making files FUD, but enough encryption on them will make them unidentifiable to any program looking for them, and that is something I can do well.
I also have 9 years of experience programming in C and C++, so I believe that there won't be a problem, and this project can be fun for us.
