Classical ciphers: Caesar, ADFGX, ROT13 and etc.

Recover the encryption key and plain text of the vigenere cipher text using Kerckhoff's method

Classical cryptanalysis tool

Educational CLI for classical cryptography. Auto-decode text, learn cipher history, encode/encrypt with 33+ classical ciphers. Pure Python stdlib.

Classical ciphers. Data Structures and Algorithms Lab, University of Helsinki (summer 2018).

Goal is to make script that archive every cipher algorithm and give users a demo of how they work

encryption and decryption algorithms in c++.

Breaking classical ciphers

Nobody has cracked Beale ciphers B1 and B3, so we modelled how you'd fake one instead. Both match the forgery within 1σ, and real English fits worse. Bayes factors for hoax: roughly 8 to 1,800 (B1) and 150 to 5,400 (B3).
