An extremely simple implementation of base64 encoding / decoding using node.js Buffers

base64.js

//
// Super simple base64 encoding / decoding with node.js
//

var base64 = exports = {
  encode: function (unencoded) {
    return new Buffer(unencoded).toString('base64');
  },
  decode: function (encoded) {
    return new Buffer(encoded, 'base64').toString('utf8');
  }
};
