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 ( His blog is at -- good coders code, great reuse.


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.)

Sincerely, Peteris Krumins
