hyuti/pwd-token-generator

A replacement of django-contrib-auth-token package in golang

pwd-token-generator

pwd-token-generator is a token generator used for use cases such as reset password, otp, etc. Basically, you will need this package in use cases where data shared between parties must be ensure its integrity and authenticity. This package is inspired by django-contrib-auth-token so that each token generated will have its timeout.

Installation

Use go get

go get -u github.com/hyuti/pwdTokenGenerator/generator

Then import the package into your own code

import "github.com/hyuti/pwdTokenGenerator/generator"

Usage

Make a token

package main

import (
	"fmt"

	"github.com/hyuti/pwdTokenGenerator/generator"
)

func main() {
	data := "data"
	// this key should be stores in enviroment variables or something similar and only accessible by you
	secretKey := "a random key"
	token := generator.MakeToken(data, secretKey)
	fmt.Println(token)
}

Validate a token

package main

import (
	"fmt"
	"time"

	"github.com/hyuti/pwdTokenGenerator/generator"
)

func main() {
	data := "data"
	secretKey := "a random key"
	token := generator.MakeToken(data, secretKey)
	timeout, err := time.ParseDuration("60s")
	if err != nil {
		fmt.Println(err)
	} else {
		err = generator.ValidateToken(data, secretKey, token, timeout)
		if err != nil {
			fmt.Printf("invalid token: %s\n", err)
		} else {
			fmt.Println("token valid")
		}
	}
}

Make a token with your own key salt

package main

import (
	"fmt"

	"github.com/hyuti/pwdTokenGenerator/generator"
)

func main() {
	data := "data"
	secretKey := "a random key"
	salt := "your own key salt"
	token := generator.MakeTokenWithSalt(salt, data, secretKey)
	fmt.Println(token)
}

Validate a token with your own key salt

package main

import (
	"fmt"
	"time"

	"github.com/hyuti/pwdTokenGenerator/generator"
)

func main() {
	data := "data"
	secretKey := "a random key"
	salt := "your own key salt"
	token := generator.MakeTokenWithSalt(salt, data, secretKey)
	timeout, err := time.ParseDuration("60s")
	if err != nil {
		fmt.Println(err)
	} else {
		err = generator.ValidateTokenWithKeySalt(salt, data, secretKey, token, timeout)
		if err != nil {
			fmt.Printf("invalid token: %s\n", err)
		} else {
			fmt.Println("token valid")
		}
	}
}
