Hill cipher online tool6/7/2023 This key matrix will be used in decryption as well. We must ensure that | Key | should not be zero otherwise we can not apply hill cipher technique. A string will be given to you and you have to make a column matrix using the letter-numberer relationship shown above. So according to this, A = 0, B = 1, C = 2. In Hill Cipher, each letter is represented by a number modulo 26. It was the first polygraphic cipher which was operable on more than 3 symbols. It works on multiple letters at the same time. This is a polygraphic substitution cipher because the substitution or encryption is performed on the block on letters. This technique was invented by an American Mathematician "Lester Sanders Hill". Now, Hill Cipher is a very basic cryptographic technique which is used to convert a string into ciphertext. Submitted by Sahil Singh, on September 28, 2019 ![]() In this article, we will learn what Hill Cipher is? It's implementation technique: How to encrypt and decrypt strings using Hill Cipher and finally, we will encrypt and decrypt a string using this technique.
