-*- mode: markup; -*- This code is based on the code from this blog posting: http://www.letsyouandhimfight.com/2010/07/14/cl-bcrypt-a-first-attempt/ I packaged it up with an .asd file, frobbed the API, and added some comments. * Installing Since this code is just a thin wrapper around a C bcrypt library you'll need one of those installed on your system. (Note that the bcrypt package available on Ubuntu and Debian does not provide this library—it is a file encryption program that uses the Blowfish algorithm.) The easiest solution is probably to get the Openwall bcrypt from http://www.openwall.com/crypt/. I’ve also put a version on Github at: https://github.com/gigamonkey/openwall-bcrypt to which I’ve added a ‘library’ target to the makefile to build the shared library. If you grab my version you can cd into the directory and ‘make library’. Then place the resulting libbcrypt.so.1.0.4 somewhere where Lisp can find it. (On OS X ~/lib will work or the cffi:*foreign-library-directories* variable may be useful here.)
