MD5 - Cryptographic Library for Lua Copyright 2003 PUC-Rio http://www.keplerproject.org/md5 MD5 offers basic cryptographic facilities for Lua 5.1: a hash (digest) function, a pair crypt/decrypt based on MD5 and CFB, and a pair crypt/decrypt based on DES with 56-bit keys. MD5 current version is 1.1.2. To install on Linux/OSX/BSD, please edit the config file and then call make make install The last step may require root privileges. If you are using LuaRocks you can also install MD5 with: luarocks install md5 History Version 1.1.2 [12/May/2008] * Fixed bug in 64-bit systems * Fixed the Windows makefile to accept longer directory names (patch by Alessandro Hecht and Ignacio Burgueño). Please check the documentation at /doc/us/ for more information. The DES 56 C library was implemented by Stuart Levy and uses a MIT license too (check the source)
