Thank you for your support!
You can install __httpntlm__ using the Node Package Manager (npm):
npm install httpntlm
``js
var httpntlm = require('httpntlm');
httpntlm.get({
url: "https://someurl.com",
username: 'm$',
password: 'stinks',
workstation: 'choose.something',
domain: ''
}, function (err, res){
if(err) return console.log(err);
console.log(res.headers);
console.log(res.body);
});
`
- url: _{String}_ URL to connect. (Required)username:
- _{String}_ Username (optional, default: '')password:
- _{String}_ Password (optional, default: '')workstation:
- _{String}_ Name of workstation (optional, default: '')domain:
- _{String}_ Name of domain (optional, default: '')agent:
- _{Agent}_ In case you want to reuse the keepaliveAgent over different calls (optional)headers:
- _{Object}_ Add in custom headers. The following headers are used by NTLM and cannot be passed: Connection, Authorization (optional)
if you already got the encrypted password,you should use this two param to replace the 'password' param.
- lm_password _{Buffer}_ encrypted lm password.(Required)nt_password
- _{Buffer}_ encrypted nt password. (Required)
You can also pass along all other options of httpreq, including custom headers, cookies, body data, ... and use POST, PUT or DELETE instead of GET.
When NTLMv2 extended security and target information can be negotiated with the server, this library assumes
the server supports NTLMv2 and creates responses according to the NTLMv2 specification (the actually supported
NTLM version cannot be negotiated).
Otherwise, NTLMv1 or NTLMv1 with NTLMv2 extended security will be used.
js
var httpntlm = require('httpntlm');
var ntlm = httpntlm.ntlm;
var lm = ntlm.create_LM_hashed_password('Azx123456');
var nt = ntlm.create_NT_hashed_password('Azx123456');
httpntlm.get({
url: "https://someurl.com",
username: 'm$',
lm_password: lm,
nt_password: nt,
workstation: 'choose.something',
domain: ''
}, function (err, res){
if(err) return console.log(err);
console.log(res.headers);
console.log(res.body);
});

If you want to use the NTLM-functions yourself, you can access the ntlm-library like this (https example):js
var ntlm = require('httpntlm').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);
});
`$3
js
httpntlm.get({
url: "https://someurl.com/file.xls",
username: 'm$',
password: 'stinks',
workstation: 'choose.something',
domain: '',
binary: true
}, function (err, response) {
if(err) return console.log(err);
fs.writeFile("file.xls", response.body, function (err) {
if(err) return console.log("error writing file");
console.log("file.xls saved!");
});
});
`$3
js
httpntlm.get({
url: "http://localhost:3000",
username: 'm$',
password: 'stinks',
workstation: 'choose.something',
domain: 'somedomain',
headers: {
'User-Agent': 'my-useragent'
}
}, function (err, res){
if(err) return console.log(err); console.log(res.headers);
console.log(res.body);
});

Running tests in an open source package is crucial for ensuring the quality and reliability of the codebase. When you submit code changes, it's essential to ensure that these changes don't break existing functionality or introduce new bugs.
Tests are written with Mocha.
To run tests, simply run:
npm test
Note that the integration tests start up a simple express.js server with NTLM support. You might see some extra debugging info from that server when running integration tests.
