A python-powered PasswordCard generator
A passwordcard is a grid of random characters that are generated using a given 64-bit seed.
The original idea for this software comes from passwordcard.org.
Original code is GPLv3, this code is AGPLv3 as it is intended to be used as a webservice.
I strived for compatibility with the original algorithm. Basically this boils down to a minimalistic reimplementation of the Java RNG, and a strict implementation of the original algorithm.
