XorIt
Most file encryptors use methods that rely on the theory of computational security, that is difficulty of key factorisation prevents decryption of the file. But this method may not work forever. It used to be considered that a 56 bit key was unbreakable to brute force attacks, but the government... This is because there is no algorithm at all, just a big key, and thus there is no pattern to follow once you have decrypted any part of the file. ... Thus attempts to decrypt it could result in any file, and there would be no way to verify that it has decrypted correctly.
