I should write up coding theory stuff as well. But for now, it is pure (basic, elementary) crypto. > >> ... > > Also, you could try using FF (like FF(3)(1) for 1 mod 3).

I posted a first version to http://boxen.math.washington.edu/home/wdj/teaching/crypto0.py Place it in sympy-0.7.1/sympy and all the examples should work. I am unsure of a few things. (a) Is the docstring formatting okay? (b) Are there enough examples? (c) Is the snippet "unique" at the bottom of the file allowed in SymPy? (I found it somewhere and don't know the copyright or license. It's a one-liner and thus might not be copyrightable.)
