httpntlm-web-maa

It's a fork from the SamDecrock httpntlm module, made to work on the browser, NOTE: it uses axios internally so the response object is the same as that of axios and the request option follows the same convention as that of axios

httpntlm is a Node.js/Browser library to do HTTP NTLM authentication

It's a port from the Python libary python-ntml

Install

You can install httpntlm-web-maa using the Node Package Manager (npm):

npm install httpntlm-web-maa

How to use

var httpntlm = require('httpntlm-web-maa');

httpntlm.get({
    url: "https://someurl.com",
    username: 'm$',
    password: 'stinks',
    workstation: 'choose.something',
    domain: '',
    ntlm: { strict: true },
    request: function(options) {
      return fetch(options.url, options);
    }
}, function(err, res) {
    if(err) return err;

    console.log(res.headers);
    console.log(res.body);
});

It supports http and https.

pre-encrypt the password

var httpntlm = require('httpntlm-web-maa');
var ntlm = httpntlm.ntlm;
var lm = ntlm.create_LM_hashed_password('Azx123456');
var nt = ntlm.create_NT_hashed_password('Azx123456');
console.log(lm);
console.log(Array.prototype.slice.call(lm, 0));
lm = new Buffer([ 183, 180, 19, 95, 163, 5, 118, 130, 30, 146, 159, 252, 1, 57, 81, 39 ]);
console.log(lm);

console.log(nt);
console.log(Array.prototype.slice.call(nt, 0));
nt = new Buffer([150, 27, 7, 219, 220, 207, 134, 159, 42, 60, 153, 28, 131, 148, 14, 1]);
console.log(nt);


httpntlm.request({
  method: 'get',
  url: "https://someurl.com",
  username: 'm$',
  lm_password: lm,
  nt_password: nt,
  workstation: 'choose.something',
  domain: '',
  ntlm: { strict: false },
  request: function(options) {
    return fetch(options.url, options);
  },
  Promise: Promise
})
.then(function(res) {
    console.log(res.headers);
    console.log(res.body);
})
.catch(function(err) {
  console.error(err);
});

/* you can save the array into your code and use it when you need it

Options

• url: {String} URL to connect. (Required)

• username: {String} Username. (Required)

• password: {String} Password. (Required)

• method: {String} method. (get,post etc...)

• workstation: {String} Name of workstation or ''.

• domain: {String} Name of domain or ''.

• ntlm: {Object} [Optional] with boolean property strict

• request: _{Function} a request function that actually does the http calls (defaults to fetch if it exists, else is Required)

• Promise: _{Class} a promise class to use (defaults to global Promise) if you already got the encrypted password,you should use this two param to replace the 'password' param.

• lm_password {Buffer} encrypted lm password.(Required)

• nt_password {Buffer} encrypted nt password. (Required)

Advanced

If you want to use the NTLM-functions yourself, you can access the ntlm-library like this (https example):

var ntlm = require('httpntlm-web-maa').ntlm;
var async = require('async');
var httpreq = require('httpreq');
var HttpsAgent = require('agentkeepalive').HttpsAgent;
var keepaliveAgent = new HttpsAgent();

var options = {
    url: "https://someurl.com",
    username: 'm$',
    password: 'stinks',
    workstation: 'choose.something',
    domain: ''
};

async.waterfall([
    function(callback) {
        var type1msg = ntlm.createType1Message(options);

        httpreq.get(options.url, {
            headers: {
                'Connection' : 'keep-alive',
                'Authorization': type1msg
            },
            agent: keepaliveAgent
        }, callback);
    },

    function(res, callback) {
        if(!res.headers['www-authenticate'])
            return callback(new Error('www-authenticate not found on response of second request'));

        var type2msg = ntlm.parseType2Message(res.headers['www-authenticate']);
        var type3msg = ntlm.createType3Message(type2msg, options);

        setImmediate(function() {
            httpreq.get(options.url, {
                headers: {
                    'Connection' : 'Close',
                    'Authorization': type3msg
                },
                allowRedirects: false,
                agent: keepaliveAgent
            }, callback);
        });
    }
], function(err, res) {
    if(err) return console.log(err);

    console.log(res.headers);
    console.log(res.body);
});

Download binary files

This will depend on your request function you send in options. So you will need to set the options related to binary download in the options variable.
