A program that encrypts plain text files using a Vigenere cipher. Version 1.0
Once the code is compiled simply run the .exe on the command line in the following format:
./VigenereCipher.exe ["Encrypt" or "Decrypt"] [Filename] [Encryption Key]
For example, if you wanted to encrypt a file called secret.txt, you would use this:
./VigenereCipher.exe encrypt secret.txt ThisIsTheSecretKey
The encrypted text will appear in the same folder as a .txt labled "CipherOutput.txt"
You can decrypt it as follows:
./VigenereCipher.exe decrypt CipherOutput.txt ThisIsTheSecretKey
The decrypted text will then be output to another file called CipherOutput.txt, overwriting the original if the name wasn't changed.
