MJCC

MJCC - Encrypt/decrypt files using Vigenére crypto.

Simple program to encrypt or decrypt files. You can set as many codewords as you like (as you can remember).

Image 1: File loaded (actually an assembler source file for a SNES emulator I worked on a long time ago called MySNES)

Image 2: Text buffer coded (= encrypted) using codeword "Codeword1". You can encode several times with the one codeword and then continue and do a couple of encodings with another. Just remember the number of encodings along with each codeword for the decryption.
