Hill cipher 2x2 examples
This is a JavaScript implementation of the Hill Cipher. The case here is restricted to 2x2 case of the hill cipher for now, it may be expanded to 3x3 later. The 'key' should be input as 4 numbers, e.g. 3 4 19 11. These numbers will form the key (top row, bottom row). key = Ciphertext See more Invented by Lester S. Hill in 1929, the Hill cipher is a polygraphic substitution cipherbased on linear algebra.

WebFeb 10, 2024 · Hill Cipher Example. As an example of the Hill Cipher technique, let’s encrypt the text, ‘ACT’, and, later, decrypt the resulting ciphertext. This will help us understand how the Hill Cipher works. To keep the example simple, here is a straightforward substitution scheme with the letter A mapped to 0, B mapped to 1, and so on and so forth. WebWhat makes the Hill cipher a block cipher is that each plaintext string is encrypted “at once:” the change of one letter in a plaintext block is likely to change all of the letters in the ciphertext block. Notice, for example, that changing the plaintext block he to ie changes the ciphertext block from GV to JA. Decryption
