go-ntlmssp

Modified from Azure/go-ntlmssp, and added Pth Mode (Pass The Hash).

Golang package that provides NTLM/Negotiate authentication over HTTP

Protocol details from https://msdn.microsoft.com/en-us/library/cc236621.aspx Implementation hints from http://davenport.sourceforge.net/ntlm.html

This package only implements authentication, no key exchange or encryption. It only supports Unicode (UTF16LE) encoding of protocol strings, no OEM encoding. This package implements NTLMv2.

Usage

url, user, password := "http://www.example.com/secrets", "robpike", "pw123"
// url, user, password := "http://www.example.com/secrets", "robpike", "8ed4a48ecd2a1276eed963da80e2256e"

client := &http.Client{
  Transport: ntlmssp.Negotiator{
    RoundTripper: &http.Transport{},
    Pth: false, // or true when using Pth Mode (Pass The Hash)
  },
}

req, _ := http.NewRequest("GET", url, nil)
req.SetBasicAuth(user, password) // password should be NTLM Hash when using Pth Mode
res, _ := client.Do(req)
