HMAC authentication for nodejs which should be compatible with Amazon.


HMAC authentication module for NodeJS.

Install the module with: npm install ofuda

Ofuda = require('ofuda');
var ofuda = new Ofuda({headerPrefix:'Amz', hash: 'sha1', serviceLabel: 'AWS', accessKeyId: '44CF9590006BF252F707', accessKeySecret: 'OtxrzxIsfpFjA7SwPzILwy8Bw21TLhquhboDYROV'});
ofuda.signHttpRequest(request); // appends a hmac authorisation header to the request 

(Coming soon)

Use as a client is illustrated below.

var http = require('http');
var Ofuda = require('ofuda');
var ofuda = new Ofuda({headerPrefix:'Amz', hash: 'sha1', serviceLabel: 'AWS', debug: true});
var credentials = {accessKeyId: '44CF9590006BF252F707', accessKeySecret: 'OtxrzxIsfpFjA7SwPzILwy8Bw21TLhquhboDYROV'};
http_options = {
    host: 'localhost',
    port: 8080,
    path: '/notify',
    method: 'PUT',
    headers: {
        'Content-Type': 'application/json',
        'Content-MD5': 'ee930827ccb58cd846ca31af5faa3634'
signedOptions = ofuda.signHttpRequest(credentials, http_options);
var req = http.request(signedOptions, function(res) {
    console.log('STATUS: ' + res.statusCode);
    console.log('HEADERS: ' + JSON.stringify(res.headers));

Use as a server is as follows.

var http = require('http'),
    Ofuda = require('ofuda');
var ofuda = new Ofuda({headerPrefix:'Amz', hash: 'sha1', serviceLabel: 'AWS', debug: true});
var validateCredentials = function(requestAccessKeyId){
    return {accessKeyId: requestAccessKeyId, accessKeySecret: 'OtxrzxIsfpFjA7SwPzILwy8Bw21TLhquhboDYROV'};
http.createServer(function (request, response) {
    if(ofuda.validateHttpRequest(request, validateCredentials)){
    } else {
        response.end('Authorization failed!');
console.log('Server running at');

In lieu of a formal style guide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using grunt.
