TWOFAP - Two Factor Authentication Program

I originally wrote a first version of a 2FA (TOTP) code generator after not being able to find a simple, easy to compile cross-platform version elsewhere. This first version was made using C++ and Qt; the source is available here.



Since then I have re-written the program in ANSI C (aka C89) using the Nuklear GUI library, in order to target more (and older) platforms, mostly for fun. The functionality of both versions is currently identical.
