Overview

Package ntlmv2hash computes weak, unsalted, hashes of passwords in the the Microsoft Windows NT LAN Manager (NTLM) protocol v2 format.

It's primary purpose is to convert passwords for use with Samba and its `pdbedit --set-nt-hash` tool. Using NTLMv2 hashes for anything else is not advised.

See `cmd` for the command-line tool.

Functions

func NTPasswordHash

func NTPasswordHash(password string) string

NTPasswordHash computes the NTLM v2 password hash.

The output is password-equivalent and easy to reverse. It must be guarded just as well as the original password.

Example

package main

import (
	"eagain.net/go/ntlmv2hash"
	"fmt"
)

func main() {
	hash := ntlmv2hash.NTPasswordHash("SecREt01")
	fmt.Println(hash)
}
