COMMENTS ON USING THIS CODE:
Normal usage is as follows:
[1] Allocate a BLOWFISH_CTX. (It may be too big for the stack.)
[2] Call Blowfish_Init with a pointer to your BLOWFISH_CTX, a pointer to
the key, and the number of bytes in the key.
[3] To encrypt a 64-bit block, call Blowfish_Encrypt with a pointer to
BLOWFISH_CTX, a pointer to the 32-bit left half of the plaintext
and a pointer to the 32-bit right half. The plaintext will be
overwritten with the ciphertext.
[4] Decryption is the same as encryption except that the plaintext and
ciphertext are reversed.
Warning #1: The code does not check key lengths. (Caveat encryptor.)
Warning #2: Beware that Blowfish keys repeat such that "ab" = "abab".
Warning #3: It is normally a good idea to zeroize the BLOWFISH_CTX before
陶慕宁freeing it.
Wa
rning #4: Endianness conversions are the responsibility of the caller.
(To encrypt bytes on a little-endian platforms, you'll probably want
to swap bytes around instead of just casting.)
Warning #5: Make sure to use a reasonable mode of operation for your
application. (If you don't know what CBC mode is, see Warning #7.)
Warning #6: This code is susceptible to timing attacks.
Warning #7: Security engineering is risky and non-intuitive. Have someone
check your work. If you don't know what you are doing, get help.
This is code is fast enough for most applications, but is not optimized for
speed.
If you require this code under a license other than LGPL, please ask. (I
can be located using your favorite search engine.) Unfortunately, I do not
have time to provide unpaid support for everyone who uses this code.
