Constants

const (
	// CookieName is the name of the jwt session cookie
	CookieName = "session_jwt"
)

Variables

var Secret string

Secret holds the hmac secret, is set from main

Functions

func Auth

func Auth(authenticated bool) gin.HandlerFunc

Auth is a gin middleware that checks for session cookie and handles permissions

func CheckDuplicate

func CheckDuplicate(name string) (check bool)

CheckDuplicate will check for duplicate name before registering

func CreateCookie

func CreateCookie(token string) *http.Cookie

CreateCookie will make a cookie for the JWT

func DeleteCookie

func DeleteCookie() *http.Cookie

DeleteCookie will delete the JWT cookie

func HashPassword

func HashPassword(password string) (hash []byte, err error)

HashPassword will create a bcrypt hash from the given password

func IsValidName

func IsValidName(name string) bool

IsValidName checks if the name is valid

func MakeToken

func MakeToken(secret string, uid uint) (newtoken string, err error)

MakeToken will create a JWT token

func Protect

func Protect() gin.HandlerFunc

Protect will check to see if a user has the correct permissions A route protected by this middleware needs an ib parameter

func RandomPassword

func RandomPassword() (password string, hash []byte, err error)

RandomPassword will generate a random password for password resets

func UpdatePassword

func UpdatePassword(hash []byte, uid uint) (err error)

UpdatePassword will update the user password hash in database

Types

type Authenticator

type Authenticator interface {
	IsValid() bool
	IsAuthorized(ib uint) bool
	SetID(uid uint)
	SetAuthenticated()
	Password() (err error)
	ComparePassword(password string) bool
	FromName(name string) (err error)
	CreateToken() (newtoken string, err error)
}

Authenticator defines the methods for authentication
