This is a node.js module, written in C++, that DES encrypts given buffer with the given key. And it actually works, compared to nonsense output that node.js's crypto module produced.
It was written by Peteris Krumins (peter@catonmat.net). His blog is at http://www.catonmat.net -- good coders code, great reuse.
About
I wrote this module so that I could add VNC Authentication in node-rfb module. Don't use it for anything else cause DES is completely broken and can be cracked in a day.
How to use it?
var ecnrypted_data = require('des').encrypt(key, data_buffer);
Note: data_buffer's length must be a multiple of 8.
How to compile?
node-waf configure build
Have fun encrypting. Not. (Don't use this module for encryption.)
