Applicable features

All cryptography should be post-quantum (this mainly removes group-based asymmetric primitives)
The program is strictly off-line, almost-non-interactive, commandline only
Algorithms that are not mainstream are better
Less code is always better
Less magic is always better

Good shape of the code

Compile with -Wall
Format the code using astyle --style=linux -xl -xk -pdtLnU -M80
Try to follow similar naming conventions as the rest of the project
Automated memory management is always better
Use a modern C++ (unlike what codecrypt started with)
