Conclusions:
- Blowfish is a 64-bit block cipher.
- 18 sub-keys are derived from a single initial key.
- Decryption algorithm is identical to the encryption algorithm except
for the order of the round keys.
- Markus Hahn provided a very efficient implementation, BlowfishJ.
Exercise: Now the algorithm is here, and the required initialization data
is here, you can try to develop your own implementation in Java.
