Interesting idea, but the actual implementation seems to be a very simple encryption scheme, for each byte, decrypted byte = plain text - key

Doesn't seem like a great encryption system, right?

The key is the same length as the data, making this a one-time pad rather than XOR encryption. http://en.wikipedia.org/wiki/One-time_pad

"rather than XOR encryption."

Nobody never mentioned that it used xor..?

XOR encryption is a one-time pad encryption over an alphabet of two letters, you might be thinking of something like a Vigenère cipher applied to binary data.

It's more of a proof-of-concept than anything else. Using the tool correctly though, I don't see any way to break it.

It's a one time pad, but working backwards. One time pads are secure, but you have to meet strict requirements for them to be secure. Those requirements are i: the pad must be truly random. ii: the pad must be unique

There's no randomness here. And there's no mention of the need for a unique pad. It's trivially crackable.

But it's a neat proof of concept.
