Automated cryptanalysis of substitution permutation network cipher

This repo is a collection of proof-of-concepts, examples, essays and experiments in cryptography, cryptanalysis, steganography and covert channels that I originally wrote in 2015.

This is a library that tries to break SPN ciphers in an fully automatic manner.

my solutions for the HW in the symmetric cipher breaking course, all the HW are exercises from the https://cryptanex.hideinplainsight.io/ website
