ntlm 1.1.0

Library for making HTTP requests that require NTLM authentication

NTLM

A library for NTLM authentication in Dart/Flutter.

Installing

Add the dependency to your pubspec.yaml file:

dependencies:
  ntlm: ^1.0.2

Example

import 'package:ntlm/ntlm.dart';

main() {
  NTLMClient client = new NTLMClient(
    domain: "",
    workstation: "LAPTOP",
    username: "User208",
    password: "password",
  );

  client.get("https://example.com/").then((res) {
    print(res.body);
  });
}

You can also pre-hash the password and use those results instead:

String lmPassword = lmHash("password");
String ntPassword = ntHash("password");

NTLMClient client = new NTLMClient(
  domain: "",
  workstation: "LAPTOP",
  username: "User208",
  lmPassword: lmPassword,
  ntPassword: ntPassword,
);

Flutter Web Support

For cross-origin requests, make sure your server includes the following header in responses:

Access-Control-Expose-Headers: WWW-Authenticate

This allows the package to view NTLM messages sent by the server.
