"WebCryptanalysis of the Affine Cipher For a recap of how the affine cipher works, see here . The affine cipher is very slightly more complicated than the Caesar cipher, but does not offer much more security. The number of possible keys is 12*26-1 = 311. This is very easy for a computer to simply search all possible keys and pick the best. " - Cryptanalyse math
