general programming stuff

Simple CLI message/file encryption tool supporting passwords or passphrases.

Encrypt & Decrypt Your messages

A simple Java application that uses AES algorithm to encrypt any text or decrypt the encrypted text back to a meaningful message.

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.

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 ,
