:nut_and_bolt: Middleware for keeping track of users, login states and permissions

Permissionbolt

Middleware for keeping track of users, login states and permissions.

Uses Bolt for the database. For using Redis as a backend instead, look into permissions2.

Features and limitations

• Uses secure cookies and stores user information in a Bolt database.
• Suitable for using Bolt database file (in a similar fashion to SQLite), registering/confirming users and managing public/user/admin pages.
• Supports registration and confirmation via generated confirmation codes.
• Tries to keep things simple.
• Only supports "public", "user" and "admin" permissions out of the box, but offers functionality for implementing more fine grained permissions, if so desired.
• Supports Negroni, Martini, Gin, Goji and plain net/http.
• Should also work with other frameworks, since the standard http.HandlerFunc is used everywhere.
• The default permissions can be cleared with the Clear() function.

Requirements

• Go 1.17 or later.

Example for Negroni

    "fmt"
    "log"
    "net/http"
    "strings"

    "github.com/codegangsta/negroni"
    "github.com/xyproto/permissionbolt/v2"
)

func main() {
    n := negroni.Classic()
    mux := http.NewServeMux()

    // New permissionbolt middleware
    perm, err := permissionbolt.New()
    if err != nil {
        log.Fatalln(err)
    }

    // Blank slate, no default permissions
    //perm.Clear()

    // Get the userstate, used in the handlers below
    userstate := perm.UserState()

    mux.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
        fmt.Fprintf(w, "Has user bob: %v\n", userstate.HasUser("bob"))
        fmt.Fprintf(w, "Logged in on server: %v\n", userstate.IsLoggedIn("bob"))

    })

    mux.HandleFunc("/makeadmin", func(w http.ResponseWriter, req *http.Request) {
        userstate.SetAdminStatus("bob")
        fmt.Fprintf(w, "bob is now administrator: %v\n", userstate.IsAdmin("bob"))
    })

    mux.HandleFunc("/clear", func(w http.ResponseWriter, req *http.Request) {
        userstate.ClearCookie(w)
        fmt.Fprintf(w, "Clearing cookie")
    })

    mux.HandleFunc("/data", func(w http.ResponseWriter, req *http.Request) {

            fmt.Fprintf(w, "list of all users: "+strings.Join(usernames, ", "))
        }
    })

    // Custom handler for when permissions are denied
    perm.SetDenyFunction(func(w http.ResponseWriter, req *http.Request) {

    n.Use(perm)

    // Use mux for routing, this goes last

Default permissions

• The /admin path prefix has admin rights by default.
• These path prefixes have user rights by default: /repo and /data
• These path prefixes are public by default: /, /login, /register, /style, /img, /js, /favicon.ico, /robots.txt and /sitemap_index.xml

The default permissions can be cleared with the Clear() function.

Password hashing

• bcrypt is used by default for hashing passwords. sha256 is also supported.
• By default, all new password will be hashed with bcrypt.
• For backwards compatibility, old password hashes with the length of a sha256 hash will be checked with sha256. To disable this behavior, and only ever use bcrypt, add this line: userstate.SetPasswordAlgo("bcrypt")

Coding style

• log.Fatal or panic shall only be used for problems that may occur when starting the application, like not being able to connect to the database. The rest of the functions should return errors instead, so that they can be handled.
• The code shall always be formatted with go fmt.

Retrieving the underlying Bolt database

Here is a short example application for retrieving the underlying Bolt database:

package main

import (
    "fmt"
    "github.com/coreos/bbolt"
    "github.com/xyproto/permissionbolt/v2"
    "os"
)

func main() {
    perm, err := permissionbolt.NewWithConf("/tmp/_tmp_bolt.db")
    if err != nil {
        fmt.Fprintf(os.Stderr, "Could not open Bolt database: %s\n", err)
        os.Exit(1)
    }
    ustate := perm.UserState()

    // A bit of checking is needed, since the database backend is interchangeable
    pustate, ok := ustate.(*permissionbolt.UserState)
    if !ok {
        fmt.Fprintln(os.Stderr, "Not using the BoltDB database backend!")
        os.Exit(1)
    }

    // Retrieve the Bolt Database from the permissionbolt.UserState
    db := (*bolt.DB)(pustate.Database())

    fmt.Printf("%v (%T)\n", db, db)
}

permissionbolt's Issues

Database Name and Access

I've read all the code and I found no way to specify the path (or name) for the bolt database. Edit: Closing issue, I missed the function the first time.

Another (unrelated) thing is, you're using your library SimpleBolt for all BoltDB access, but I think there should be a way to expose the SimpleBolt object (I think there is), but should be documented. I'm already using BoltDB on my project and after seeing SimpleBolt I might use that too, but I think there is no point on tracking both database objects. SimpleBolt should also expose the underlying BoltDB object for things like backup and such.

FindUserByConfirmationCode fails because of HasUser check

Hello

For the use case of verifying a user by having them click a link with the confirmation code as a URL parameter:

When calling UserState.FindUserByConfirmationCode() to find the uncomfirmed user whose confirmation code is the one specified in the URL query string, the function finds the candidate username and then does the following check (link to the relevant line in source code):

hasUser := state.HasUser(username)

The issue is that HasUser() has the following check:

state.usernames.Has(username)

which, for unconfirmed users, it fails. It really should also do the check on the state.unconfirmed Set.

Note that calling UserState.ConfirmUserByConfirmationCode() fails the same way, because the very first thing it does is call FindUserByConfirmationCode().

Having said all this, maybe I'm using the library incorrectly for the use case described at the beginning.

Thanks!

userstate available outside of main()

Hi there,

Just a quick question (apologies if this is obvious), in the echo example "userstate" is available only inside of main(). How do I make userstate available outside of the main() function, say for example if I have a bunch of handlers funcs separate from the main func?

Get all fields for a user

Hello

I'm looking to list all fields stored for a user. Any way to access the data without knowing the keys? I think it will be like the state.users.Get(username, ) function, but take only a username as the argument and return a map of key:value pairs.

Thanks!

Why is the code for gin and macaron longer than those for Negroni and Martini

Out of curiosity, why is the middleware code for gin and macaron longer than those for Negroni and Martini?

pdkdf

Add support for the pdkdf2 algorithm. There's a fork that have already done this, for inspiration: nsjph/permissionbolt.

*UserState missing CookieSecret()

Bit of noob, please be kind if I'm messing up here...

I'm vendoring packages using the new dep tool and I'm using permissionbolt.

The latest release of pinterface (v4.0.0) and HEAD, introduces a new method to the pinterface.IUserState interface, CookiSecret.

permissionbolt relies on pinterface package but does not implement this interface because UserState doesn't have a CookieSecret method.

If you use the HEAD of permissionbolt and pinterface, or your vendoring tool gets the latest releases of these packages, you end up with a build error like this:

../../vendor/github.com/xyproto/permissionbolt/permissionbolt.go:69: cannot use perm.state (type *UserState) as type pinterface.IUserState in return argument:
*UserState does not implement pinterface.IUserState (missing CookieSecret method)

I think I've wangled dep to give me v2.0.0 of pinterface and the build now works. But you may want to ensure the HEADs of each project are compatible.

Cheers!

Compile error with vendors

Hi

$ go version
go version go1.13.4 linux/amd64

When trying to build a server with permissionbolt included as an import, I get:

# github.com/xyproto/permissionbolt
../../../github.com/xyproto/permissionbolt/userstate.go:595:30: cannot use simplebolt.NewCreator(state.db) (type *simplebolt.BoltCreator) as type "github.com/xyproto/pinterface".ICreator in return argument:
	*simplebolt.BoltCreator does not implement "github.com/xyproto/pinterface".ICreator (wrong type for NewHashMap method)
		have NewHashMap(string) ("github.com/xyproto/simplebolt/vendor/github.com/xyproto/pinterface".IHashMap, error)
		want NewHashMap(string) ("github.com/xyproto/pinterface".IHashMap, error)

I tried lots of different things (like go get -u all, removing the vendors directory), but nothing worked. Any ideas?

Thanks.
