This repository contains the algorithm for the Hill Cipher encryption which use the matrix to encrypt the message and even to decrypt it using the inverse of the same matrix ,this algorithm uses the python program to implement it and of course we can use any language to implement it ,
Caesar Cipher w/o GUI. Enter a message and a key (number from 1-26) and receive an enciphered message back. Also has decipher functionality if you know the key.
Shell script that does simple encryption/decryption algorithm for text messages with only alphabet characters. This encryption/decryption is based on the use of XOR logic gate.
