Web2 days ago · I am trying to solve a substitution cipher with dictionary keys and a rotation shift. For example: keys: 'A':'Z', 'B':'Y', 'C':'X' and so on..... plaintext = AAABBB. cipher text with 0 rotation = ZZZYYY. cipher text with 1 rotation = ZYXVUT. Identical letters are encoded differently because encoder increments the letter by rotation every time ... http://inventwithpython.com/cracking/
