WebRot Cipher. The Rot Cipher is when you take a letter and put it back or fourth to equal a different letter. An example of this would be -1 equals A=Z. +1 equals A+B It is Related to the Caesar Cipher. This is a Print out of the Rot Cipher Wheel. Cut out the 2 circles leaving the inner circle NOT HOLLOW. 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 ...
