httpsigver-ap

httpsigver-ap is a Go library allowing everyone to easily add Mastodon/ActivityPub-compatible HTTP signature to any HTTP request as well as verify the validity of a request's signature originating from an ActivityPub server.

Usage

Signing requests

package main

import (
	//...
	
	"github.com/MatejLach/httpsigver-ap"
)

func main() {
	// ...
	req, err := http.NewRequest(http.MethodGet, fmt.Sprintf("%s/user/me", server.URL), nil)
	if err != nil {
		// error handling
	}

	reqActorPubKeyId, err := url.Parse(fmt.Sprintf("%s/user/me", server.URL))
	if err != nil {
		// error handling
	}

	err = httpsigver.SignRequest(context.Background(), req, reqActorPubKeyId, privateKeyPem.String())
	if err != nil {
		// error handling
	}
}

Verifying requests

package main

import (
	//...
	
	"github.com/MatejLach/httpsigver-ap"
)

func main() {
	// ...
	validSignature, err := httpsigver.ReqHasValidSignature(context.Background(), req, "", true)
	if err != nil { 
		// error handling
	}
}

See the test suite for a more complete example.
