HSig0

Go library to validate dns messages using Handshake sig0. You can use it to resolve names over the handshake network and verify them using the node's public key.

Usage

package main

import (
	"fmt"
	"github.com/buffrr/hsig0"
	"github.com/miekg/dns"
	"log"
)

func main() {
	k, err := hsig0.ParsePublicKey("aj7bjss4ae6hd3kdxzl4f6klirzla377uifxu5mnzczzk2v7p76ek")
	if err != nil {
		log.Fatal(err)
	}

	// basic dns query
	client := new(dns.Client)
	query := new(dns.Msg)
	query.SetQuestion("proofofconcept.", dns.TypeA)

	msg, _, err := client.Exchange(query, "192.168.1.21:8181") // node ip:port
	if err != nil {
		log.Fatal(err)
	}

	if err := hsig0.Verify(msg, k) ; err != nil {
		log.Fatal(err)
	}

	fmt.Println("Success ✔️")
	fmt.Println(msg)
}
