WebI am trying to cryptanalyse a cipher–text encrypted by Affine cipher. The encryption formula is: c = f ( x) = ( a x + b) mod m, where a and b are unknown constants; x is a plain-text symbol, and c the corresponding cipher-text symbol, both in range [ 0 … m − 1]; m = 26 is known. That means that letter 4 has been encrypted into 17 (numbers ...
