What is hawk?

The 'hawk' npm package is a security-oriented library that provides HTTP authentication using the Hawk protocol. It is designed to help developers implement secure communication between clients and servers by ensuring message integrity and authenticity.

What are hawk's main functionalities?

Message Authentication

This feature allows you to generate an HTTP Authorization header for a request, ensuring that the request is authenticated and has not been tampered with. The code sample demonstrates how to create a Hawk client header using provided credentials.

const Hawk = require('hawk');

const credentials = {
  id: 'dh37fgj492je',
  key: 'aoijedoaijsdlaksjdl',
  algorithm: 'sha256'
};

const header = Hawk.client.header('http://example.com/resource/1?b=1&a=2', 'GET', { credentials: credentials, ext: 'some-app-data' });
console.log(header.field);

Server Authentication

This feature allows you to authenticate incoming HTTP requests on the server side. The code sample demonstrates how to set up a simple HTTP server that uses Hawk to authenticate requests.

const Hawk = require('hawk');

const credentialsFunc = function (id, callback) {
  const credentials = {
    id: id,
    key: 'aoijedoaijsdlaksjdl',
    algorithm: 'sha256'
  };
  return callback(null, credentials);
};

const server = require('http').createServer((req, res) => {
  Hawk.server.authenticate(req, credentialsFunc, {}, (err, credentials, artifacts) => {
    if (err) {
      res.writeHead(401);
      res.end('Unauthorized');
      return;
    }
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end('Hello ' + credentials.user);
  });
});

server.listen(8000);

Bewit (URL) Authentication

This feature allows you to generate a 'bewit' token for URL-based authentication. The code sample demonstrates how to create a bewit token that can be appended to a URL for temporary access.

const Hawk = require('hawk');

const credentials = {
  id: 'dh37fgj492je',
  key: 'aoijedoaijsdlaksjdl',
  algorithm: 'sha256'
};

const bewit = Hawk.uri.getBewit('http://example.com/resource/1?b=1&a=2', { credentials: credentials, ttlSec: 60 });
console.log(bewit);
