GoJARM

GoJARM is an implementation of JARM in Go.

Usage

The usage is very simple, below is an example of how to get started

package main

import (
	"fmt"

	"github.com/TheGejr/gojarm"
)

func main() {
	target := gojarm.Target{
		Host: "github.com",
		Port: 443,
		Retries: 5,
	}

	res := gojarm.Fingerprint(target)

  if res.Error != nil {
    fmt.Println(res.Error)
  }

	fmt.Printf("Domain: %s\n", res.Target.Host)
  fmt.Printf("JARM: %s\n", res.Hash)
}

Known errors

Currently there is some errors with the implementation, so it shouldn't be used in production yet. Running the official implentation on the alexa500.txt provided in JARM and running gojarm on the same list produces a diffrent JARM hash for 14 domains.
