	"log"

	"github.com/nasermirzaei89/jwt"
)

func main() {
	token := jwt.New(jwt.HS256)
	tokenStr, err := jwt.Sign(*token, []byte("secret_key"))
	if err != nil {
		log.Fatalln(err)
	}

	fmt.Println(tokenStr) // eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.e30.HUfJqC1q8JUPKD4jj8PZAYppSrQRL8tJHTljdcTfFCQ
}

Verify

package main

import (

func main() {
	tokenStr := "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.e30.HUfJqC1q8JUPKD4jj8PZAYppSrQRL8tJHTljdcTfFCQ"
	err := jwt.Verify(tokenStr, []byte("secret_key"))
	if err != nil {
		log.Fatalln(err)
	}
}

)

func main() {
	token := jwt.New(jwt.HS256)
	token.SetIssuer("https://yourdomain.tld")
	token.SetExpirationTime(time.Now())
	tokenStr, err := jwt.Sign(*token, []byte("secret_key"))
	if err != nil {
		log.Fatalln(err)
	}

	fmt.Println(tokenStr) // variable
