Blowfish

Blowfish is a 64-bit encryption algorithm, with a key length between 32 and 448 bits. There are a few different takes on it in CL (some targeting specific Common Lisp implementations):

• Ironclad includes support for Blowfish.
• Alain Picard wrote a Blowfish implementation with optimizations for CMUCL and SBCL, released under LLGPL.
• Another blowfish.lisp was developed by Joern Inge Vestgaarden using CMUCL, and released under LGPL.
• Allegro CL provides its own Blowfish implementation.
