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 🙏

Module de cryptage de mots de passe - SHA1 encryption

Readme

@dan/iut-encrypt

Module NPM de cryptage de mots de passe permettant de simplifier les appels du module encrypt fourni par Node.JS.

Installation

npm install @dan/iut-encrypt

Utilisation

'use strict';

const Encrypt = require('@dan/iut-encrypt');

const plainTextPassword = 'motdepasse';

// Encoder un mot de passe en SHA1
const passwordSha1 = Encrypt.sha1(plainTextPassword);

// Comparer un mot de passe saisi avec le hash stocké
if (Encrypt.compareSha1('motdepassesaisit', passwordSha1)) {
    console.log('Connexion validée');
} else {
    console.log('Connexion refusée');
}

API

sha1(plainTextPassword)

Encode un mot de passe en SHA1.

Paramètres:

  • plainTextPassword (string): Le mot de passe en clair

Retour:

  • (string): Le hash SHA1 du mot de passe

Exemple:

const hash = Encrypt.sha1('monmotdepasse');
// hash = '9c1c3d5e73f2b5d5c8e1f5b5d5c8e1f5b5d5c8e'

compareSha1(plainTextPassword, hashedPassword)

Compare un mot de passe en clair avec son hash SHA1.

Paramètres:

  • plainTextPassword (string): Le mot de passe en clair à vérifier
  • hashedPassword (string): Le hash SHA1 à comparer

Retour:

  • (boolean): true si les mots de passe correspondent, false sinon

Exemple:

const hash = Encrypt.sha1('motdepasse');
const isValid = Encrypt.compareSha1('motdepasse', hash);
// isValid = true

Architecture Modulaire

Ce module est conçu comme évolutif pour permettre l'ajout de nouvelles méthodes de cryptage dans le futur:

  • sha1() - Cryptage SHA1 (actuellement implémenté)
  • Futures méthodes possibles: sha256(), bcrypt(), md5(), etc.

Mode Strict

Le module utilise le mode strict ('use strict') qui:

  • Élimine les erreurs silencieuses en les changeant en erreurs explicites
  • Améliore les performances d'exécution
  • Interdit les mots-clés susceptibles d'être définis dans les futures versions d'ECMAScript

Tests

npm test
