WebFeb 4, 2024 · C++ Program to Implement the Hill Cypher. Based on linear algebra Hill cipher is a polygraphic substitution cipher in cryptography. To encrypt message: The key string and message string are represented as matrix form. They are multiplied then, against modulo 26. The key matrix should have inverse to decrypt the message. WebHill Cipher using a 2 x 2 Key Matrix. I'm new to cryptography and I cannot seem to get my head around this problem: The problem says that the Hill Cipher using the below 2 x 2 key …
WebNov 20, 2024 · so that the inverse of 7 is − 11 ≡ 15. So we multiply all elements of. [ 2 − 7 − 3 1] by 15 to get the inverse matrix we're looking for (of course all modulo 26) and we get. [ 4 18 7 15] and now you can do the multiplication from the first equation modulo 26: [ − 9 − 2 − 2 9] [ 4 18 7 15] to find the encryption matrix E.
