Correct me if I’m wrong, but is a Vigenère cipher where key length=text length just a One-Time Pad? I remember we had some fun a few years back with the concept of Two-Time Pads, since a One-Time Pad is mathematically proven to be uncrackable (for the very reason that you can decipher a ciphertext into any text you like given a specific key).
