# go-ntlmssp
|
||||
Golang package that provides NTLM/Negotiate authentication over HTTP
|
||||
|
||||
[](https://godoc.org/github.com/Azure/go-ntlmssp) [](https://travis-ci.org/Azure/go-ntlmssp)
|
||||
|
||||
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"
|
||||
client := &http.Client{
|
||||
Transport: ntlmssp.Negotiator{
|
||||
RoundTripper:&http.Transport{},
|
||||
},
|
||||
}
|
||||
|
||||
req, _ := http.NewRequest("GET", url, nil)
|
||||
req.SetBasicAuth(user, password)
|
||||
res, _ := client.Do(req)
|
||||
```

# Contribution Guidelines
|
||||
|
||||
We welcome contribution and improvements.
|
||||
|
||||
## Guiding Principles
|
||||
|
||||
To begin with here is a draft from an email exchange:
|
||||
|
||||
* take compatibility seriously (our semvers, compatibility with older go versions, etc)
|
||||
* don't tag untested code for release
|
||||
* beware of baking in implicit behavior based on other libraries/tools choices
|
||||
* be as high-fidelity as possible in plumbing through LDAP data (don't mask errors or reduce power of someone using the library)

||||
