WebFeb 20, 2024 · One way to look at it is that the Vigenère cipher is a way to generate a pad like a one-time pad, except each letter in the pad is related to the last one, and it repeats, so it's not a very good way to generate a pad. A much better way to generate a pad is, for example, using the ChaCha stream cipher with a 256-bit key. – Squeamish Ossifrage WebIn order to visualize the strength of the one-time pad, we must understand the combinatorial explosion which takes place.
