    Base 64 encoding is not encryption. What is this encryption for?
    C + C++ Compiler: MinGW port of GCC
    Build + Version Control System: SCons + Bazaar

    Well... the simplest encoding I can think of is to do none at all. That will maintain your file size. As a bonus, it is very efficient. Optimal, in fact.

    So, what is this encoding for?
