Short description of CryptIt 1.4: Most file encryptors use methods that rely on the theory of computational security, that is the difficulty of key factorisation prevents decryption of the file. But this method may not work forever. CryptIt is designed to use XOR encryption on keys that are the same size as the file to be encrypted. CryptIt also has a ability to use removable media as a key code book and integrates with the key generator built into our program GigAlarm.
