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

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. Hill used matrices and matrix multiplication to mix up the plaintext. To … See more This example will rely on some linear algebra and some number theory.

WebOutput example of the Hill cipher implementation Advantages of Hill cipher. The main advantage of the Hill cipher is that it hides single letter frequency. Depending on how big the matrix that represents the key is, the more letter frequency it hides. For instance, if you use a 3×3 matrix, it hides single letter and two-letter frequencies.
