cryptonite

Encryption & decryption and signing of objects for node.js made simple.

It's slim wrapper on top of node.js library. Useful for for example secure storing values in cookies.

Example

example for express js cookies

var Cryptonite = require('cryptonite');
var cookie = require('cookie');

var cryptonite = new Cryptonite({
                                    cryptoSecret: 'very secret crypto secrect',
                                    signingSecret: 'very secret signing secrect'
                                });
                                
var authenticationTicket = {
              userId: '3456798764',
              token: '234567895345764857864237654345764'
          };

var encryptedAuthenticationTicket = cryptonite.encrypt(authenticationTicket);

res.cookie('auth_cookie',encryptedAuthenticationTicket, {
                                                    httpOnly: true,
                                                    maxAge: 86000
                                                });

var cookies = req.headers.cookie;
var parsedCookies = cookie.parse(cookies);
var authCookieValue = parsedCookies['auth_cookie'];


var retreivedAuthenticationTicket = cryptonite.decrypt(authCookieValue);
