WebDec 17, 2016 · With this property of Hill Cipher we can go about cracking it. First you will need to identify N (the size of the matrix) the size will be a multiple of the text length – this narrows it down a lot. Now you will be to iterate over all the row vectors with a size of N and possible values of 0 (inclusive) to 26 (exclusive). 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 ...
