SBXOR

Purpose

Given an encoded string try all 256 bytes with a single byte xor operation across the string. Can determine if a string contains English

How to use

Add the crate to [dependencies] and specify the lastest version. Then bring it into scope by placing extern crate sbxor; followed by use sbxor::* in a source file where the functionality is desired.

How it works

Iterates over all 256 possible u8s and xors them against the provided string. Non-ascii characters are stripped. There will be 256 possible decoded strings, some having the is_english field set. The field indicates that there is an English word longer than 3 characters resulting from the xor process.

lib.rs:

Single byte XOR against string.

Sbxor takes a string argument that has been encoded with a single byte XOR. Following that it decodes it, and determines if it contains English words.
