JOWT (JWT Simple Package for Golang)

JOWT is a Simple Package for Golang to generate and verify JWT Token using HMAC + RSA256 OR RSA512.

How to Install ?

$ go get github.com/johansetia/jowt

How to Use ?

1. Importing Package

package main

import (
    "github.com/johansetia/jowt"
)

2. Make a Payload and Key

you can use a structure from this package to create payload data.

key := "qwertyuiopasdfghjklzxcvbnm123456"
data := jowt.Payload{
	"iss": "johan.com",
        "iat": 1566959060,
        "exp": 1598495060,
        "aud": "www.johan.com",
        "sub": "admin@johan.com",
        "UserName": "Johan",
        "Email": "johan@example.com",
        "userData": jowt.Payload{
                "Level":     "Administrator",
                "Role":      "UserAdministrator",
            },
	}

3. Getting value

Using HS512 Function to get a JWT Token

    token, ok := jowt.HS512(key).SetPayload(dataPayload).Get()
    if !ok {
        panic("ERROR GET TOKEN")
    }
    fmt.Println(token)
    

Your HS512 token is

Using HS256 Function to get a JWT Token

    token, ok := jowt.HS256(key).SetPayload(dataPayload).Get()
    if !ok {
        panic("ERROR GET TOKEN")
    }
    fmt.Println(token)
    

Your HS256 token is

eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJFbWFpbCI6ImpvaGFuQGV4YW1wbGUuY29tIiwiVXNlck5hbWUiOiJKb2hhbiIsImF1ZCI6Ind3dy5qb2hhbi5jb20iLCJleHAiOjE1OTg0OTUwNjAsImlhdCI6MTU2Njk1OTA2MCwiaXNzIjoiam9oYW4uY29tIiwic3ViIjoiYWRtaW5Aam9oYW4uY29tIiwidXNlckRhdGEiOnsiTGV2ZWwiOiJBZG1pbmlzdHJhdG9yIiwiUm9sZSI6IlVzZXJBZG1pbmlzdHJhdG9yIn19.yoFC0whrAh80A0bc7bGMlDR3XRW_dL-YwwEXQ3qRlJQ

4. Verify your JWT using key

    verify := jowt.Verify(key).SetToken(jwt).Status()
    if verify {
        fmt.Println("USER ACCEPTED")
    }else{
        fmt.Println("USER DECIDED")
    }
