The basic modulation function of a multiplicative cipher in Python is as follows − def unshift(key, ch): offset = ord(ch) - ASC_A return chr(((key[0] * (offset + key[1])) % WIDTH) + ASC_A) Note − The advantage with a multiplicative cipher is that it can work with very large keys like 8,953,851. WebThe multiplicative cipher is like the Caesar cipher from Chapter 6, except it uses multiplication instead of addition. The affine cipher is the multiplicative cipher, which is then encrypted by the Caesar cipher on top of that. ... Here is the source code for a Python program that implements the affine cipher.
