gistfile1.js

var crypto = require('crypto');

var origtoken = '128073137281613|2.AQDnAjjO73ESnmhJ.3611.1311634811.2-3306278|i3L2dgZ7rg6m2vKt0GzjhhKbzTQ';

var algo = 'des-ecb'; // openssl list-cipher-commands  to list available algos
var key  = 'appelsap';
var base = 'base64'; // changing this to 'hex' makes it work

var tokencrypt = crypto.createCipher(algo, key);

var token = tokencrypt.update(origtoken, 'ascii', base)+tokencrypt.final(base);

//console.log(token);

tokencrypt = crypto.createDecipher(algo, key);

token = tokencrypt.update(token, base, 'ascii')+tokencrypt.final('ascii');

console.log(token);
console.log(origtoken);

// Prints:
