ByteBreak 1.0

Description

"ByteBreak is a quick & easiest way to decipher strings."
Brothersoft Editor: Anti-virus researchers and software developers know that simple ciphers are surprisingly common, especially considering their obvious weaknesses. So why are such ciphers used at all? The reason is usually because the advantages sometimes outweigh the disadvantages, strong security isn't always required, or the person who encrypted it thought the encryption strength was sufficient for the task.

ByteBreak is a quick & easiest way to decipher strings that have been encrypted this way, and at just 20kb it does everything you need and nothing you don't.

Let's look at the main pros and cons of using simple XOR ciphers.
Advantages:
- Speed: Very little computation is involved so encryption and decryption are both very quick.
- Size: They require very little code, something that is especially important in 'shellcode' injections where code size can be extremely limited.
- Ease: They're quick and easy to implement, and even novice programmers with no experience in cryptography find them easy to use.
Disadvantages:
- Appearance: Text strings that have been enciphered this way still look scrambled and often retain a pattern (as opposed to random data). Such strings easily stand out to anti-virus researchers.
- Weak: In the case of XOR and ADD/SUB ciphers where a single byte is used as the key there are only 255 combinations (1-255), making brute force cracking trivial.

It is this weakness that ByteBreak exploits. you can free download ByteBreak 1.0 now.
