Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

SDK JavaScript pour l'authentification des agents KYA

Readme

@platform-auth/kya-sdk-js

SDK JavaScript pour l'authentification des agents IA — KYA (Know Your Agent).

Présentation

Ce SDK permet à un agent IA de prouver son identité auprès d'une API backend (Laravel) grâce à un système de signature cryptographique Ed25519.

Le flux est simple :

  1. L'agent génère un couple de clés (publique + secrète).
  2. La clé publique est enregistrée côté serveur lors de l'enrôlement.
  3. À chaque requête, l'agent signe un message (ex : un challenge ou un timestamp) avec sa clé secrète.
  4. Le serveur vérifie la signature avec la clé publique enregistrée.

Installation

npm install @platform-auth/kya-sdk-js

Utilisation

Générer un couple de clés

import { KyaAuth } from '@platform-auth/kya-sdk-js';

const { publicKey, secretKey } = KyaAuth.generateKeyPair();

console.log('Clé publique :', publicKey);
console.log('Clé secrète :', secretKey);
// Stocker la clé secrète de manière sécurisée
// Envoyer la clé publique au serveur lors de l'enrôlement

Signer un message

const kya = new KyaAuth({ baseUrl: 'https://mon-api.com/api' });

const message = 'challenge-unique-du-serveur';
const signature = kya.signMessage(message, secretKey);

// Envoyer la signature dans le header ou le body de la requête

Vérification côté serveur (Laravel)

Le serveur reçoit le message + la signature, puis vérifie avec la clé publique de l'agent enregistrée en base. Si la signature est valide, l'identité de l'agent est confirmée.

API

| Méthode | Description | |---------|-------------| | KyaAuth.generateKeyPair() | Génère un couple { publicKey, secretKey } encodé en Base64 | | kya.signMessage(message, secretKeyBase64) | Signe un message et retourne la signature en Base64 |
