內容說明:
CryptIt是一款文件加密工具，採用傳統的XOR加密技術，如果密鑰不洩漏，加密是不可破解的。
英文說明:
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. It used to be considered that a
56 bit key was unbreakable to brute force attacks, but the
government of the USA now requires all Top Secret data to
use keys of at least 192 bits. This bar will keep raising as
computing power increases. (It is argued by some though that
this will never happen due to the laws of physics!) CryptIt
is designed to use conventional XOR encryption on keys that
are the same size as the file to be encrypted. Furthermore,
if you use an unpredictable file that is the same size (or
larger) than the original file and you use this file only
once, this is known as a one-time pad and it is completely
unbreakable, even to computers 1000 years from now. 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. CryptIt can also has some
convenience features such as being able to automatically use
pad files generated by our program GigAlarm, generate key
files (from a stream cipher and thus not best for OTP usage)
and also analyse the suitability of your chosen key file.
