* Description: Eric Young's test vectors for Blowfish.
*
* PasswordSafe Note: To pass these tests, I had to change the
* order of the bytes in the plaintext and ciphertext vectors,
* from {3,2,1,0,7,6,5,4} to {0,1,2,3,4,5,6,7}. This is either a
* (cryptographically benign) bug in the implementation, or some
* endian-ness oddity in the test data. My guess is the former.
