This is the problem I have to figure out:
“A message has been encryption using Vigenere encryption method discussed
in class, and its cipher text EQNVZ has been intercepted. Break the code. Assume
that the key is the same length as the message, and the message and the key
consist only of uppercase letters.”
Is there are way to do this in python? I know there is a way to make a cipher text in python, but is there a way to go the other way?
It is a trick question. If “the key is the same length as the message” then you have a one-time pad that conceals everything except the message length.
