HTTP Authentication implementation in Go

Build Status codecov

This is an implementation of HTTP Basic in Go language. Which is basically a mash-up of abbot/go-http-auth and GehirnInc/crypt

Features

  • Supports HTTP Basic
  • Supports htpasswd formatted files.
  • Automatic reloading of password files.
  • Pluggable interface for user/password storage.
  • Supports MD5, SHA1 and BCrypt for Basic authentication password storage.
  • Configurable Digest nonce cache size with expiration.
  • Wrapper for legacy http handlers (http.HandlerFunc interface)

Example usage

This is a complete working example for Basic auth:

package main

import (
        "fmt"
        "net/http"

        auth "github.com/wolviecb/basic-auth"
)

func Secret(user, realm string) string {
        if user == "john" {
                // password is "hello"
                return "$apr1$Xfu5Jqwg$DYvBqzdcW84tnuq5SbnZE/"
        }
        return ""
}

func handle(w http.ResponseWriter, r *auth.AuthenticatedRequest) {
        fmt.Fprintf(w, "<html><body><h1>Hello, %s!</h1></body></html>", r.Username)
}

func main() {
        authenticator := auth.NewBasicAuthenticator("example.com", Secret)
        http.HandleFunc("/", authenticator.Wrap(handle))
        http.ListenAndServe(":8080", nil)
}
