Elm implementation of encryption using an SPN with a front-end

An implementation of a substitution-permutation-network and a randomized counter CTR

Implementation of an SP Network using a new modified Playfair Cipher for substitution and the chaotic Logistic-Tent Map for permutation, in Python. This new algorithm has been named Playfair Logistic-Tent Network (PLT-Net).
