- The Crypt::Blowfish_PP module provides for users to use the Blowfish
- encryption algorithm in perl. The implementation is entirely Object
- Oriented, as there is quite a lot of context inherent in making blowfish
- as fast as it is. The key is anywhere between 64 and 448 bits (8 and 56
- bytes), and should be passed as a packed string. The transformation
- itself is a 16-round Feistel Network, and operates on a 64 bit block.
