WebNov 20, 2024 · 1 I'm trying to find the Hill Cipher key from the following given info: (1,3)^T is encrypted as (-9, -2)^T, and (7, 2)^T is encrypted as (-2, 9)^T. However I don't seem to end up with the correct answer as the encryption is invalid when I try to use the key. Below is my solution, did I make a mistake somewhere? So [ a b c d] [ 1 3] = [ − 9 − 2] and WebHill cipher is an alternative cipher that uses the principles of basic matrix theory. It is now mostly used in classical cipher teaching and learning.

WebJun 19, 2024 · 1 Answer Sorted by: 1 Assuming that 2 × 2 matrix is used, and the encryption starts from the first letter of the plaintext, the key can be found by just calculating the "encryption" with size of 4 plain- and cryptotext block. For example, for CONV → SQZH, it would go as follows: ( 2 14 13 21) ( a b c d) = ( 18 16 25 7) ( mod 26)
