ARM Cipher

What it does?

Encipher and deciphers a piece of text using a caesar cipher. Built completely using ARM assemblya and allows you to encipher/decipher any input with a given private key.

So does it work?

Yes. Example of use:

cat textfile.txt | ./cw2 0 lock. 

Use 0 as a parameter to encrypt the input and 1 to decrypt followed by the private key (e.g. "lock"). This will encrypt/decrypt whetever is piped through.

Why was it made?

Primarily made as a way of learning about operating systems and assembly language.
