<h3 id="analyse">Analyse</h3>
<ul>
<li><a href="https://unmitigatedrisk.com/?p=241">Priming the OCSP cache in Nginx</a></li>
</ul>
<p>Donc, récemment, GlobalSign, DigiCert et Comodo ont travaillé avec Nginx pour obtenir lagrafage OCSP pris en charge dans Nginx 1.3.7, malheureusement, les restrictions architecturales ont rendu la mise en œuvre impossible de sorte que la pré-récupération de la réponse OCSP au démarrage du serveur soit donc la première connexion. au serveur amorce le cache utilisé pour les connexions ultérieures.</p>
<p>Cest un bon compromis, mais que faire si vous voulez vraiment que la première connexion ait également lavantage? Eh bien, vous pouvez adopter deux approches:</p>
<ol>
<li>Juste après avoir démarré le serveur, vous effectuez une demande SSL pour amorcer le cache.
<ul>
<li>Vous obtenez manuellement la réponse ocsp et laplombez là où Nginx la recherche.</li>
</ul>
</li>
</ol>
<p>Le <u>premier modèle</u> est facile, juste après avoir démarré votre serveur, utilisez le <code class="language-plaintext highlighter-rouge">s_client</code> OpenSSL pour vous connecter au serveur avec lagrafage OCSP activé comme je lai documenté dans cet <a href="https://unmitigatedrisk.com/?p=100">article</a> , la première demande déclenchera la récupération de la réponse OCSP par Nginx.
Le <u>deuxième modèle</u> peut être fait avant de démarrer le serveur, vous devez trouver lURI du répondeur OCSP, faire une demande OCSP et remplir manuellement le cache Nginx, cela ressemblerait à:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>#!/bin/sh
ISSUER_CER=$1
SERVER_CER=$2
URL=$(openssl x509 -in $SERVER_CER -text | grep “OCSP URI:” | cut -d: -f2,3)
openssl ocsp -noverify -no_nonce -respout ocsp.resp -issuer \
$ISSUER_CER -cert $SERVER_CER -url $URL
</code></pre></div></div>
<p>Où «ocsp.resp» correspond au fichier que vous avez configuré dans Nginx pour le « ssl_stapling_file ».</p>
<p>Chaque approche a ses avantages et ses inconvénients, par exemple avec la première approche, votre exécution de lappel s_client peut ne pas être la première demande que le serveur voit, avec la deuxième approche si vous utilisez un certificat qui ne contient pas de pointeur OCSP et que vous avez dit manuellement à Nginx où récupérer létat du certificat, alors cela ne fonctionnera pas.</p>
<p>Il convient de noter que vous pouvez exécuter ce même script dans un script cron pour vous assurer que votre serveur na jamais besoin de toucher le câble (et potentiellement de le bloquer en le faisant) lorsquil essaie de garder son cache OCSP à jour.</p>
<h3 id="solution">SOLUTION</h3>
<p>Créer un bash universel avec le nom de domaine comme paramètre<br>
Les noms de de fichier pour chaque domaine ou sous domaine sont de la forme <code class="language-plaintext highlighter-rouge">*domaine.conf</code><br>
Les fichiers <code class="language-plaintext highlighter-rouge">*.conf</code> dans le dossier <strong>/etc/nginx/conf.d/</strong></p>
<p>Créer le bash nommé <strong>ocsp_cache</strong> dans le dossier <strong>/usr/local/bin/</strong></p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo nano /usr/local/bin/ocsp_cache
</code></pre></div></div>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>#! /bin/sh

<h2 id="openssl-ocsp-vérification-certificat">OpenSSL OCSP vérification certificat</h2>
<p>Cet article vous montre comment vérifier manuellement un certificat sur un serveur OCSP. OCSP est lacronyme de Online Certificate Status Protocol et est un moyen de valider un état de certificat. Il sagit dune alternative à la liste de révocation de certificats CRL.</p>
<p>Par rapport aux CRL:</p>
<ul>
<li>Dans la mesure où une réponse OCSP contient moins dinformations quune CRL (liste de révocation de certificats) classique, OCSP peut utiliser plus efficacement les réseaux et les ressources client.</li>
<li>Avec OCSP, les clients nont pas besoin danalyser eux-mêmes les listes de révocation de certificats, ce qui réduit la complexité côté client. Cependant, cela est contrebalancé par la nécessité pratique de maintenir un cache. Dans la pratique, de telles considérations sont peu importantes, car la plupart des applications sappuient sur des bibliothèques tierces pour toutes les fonctions X.509.</li>
<li>OCSP révèle au répondant quun hôte réseau particulier a utilisé un certificat particulier à un moment particulier. OCSP ne rend pas obligatoire le cryptage, donc dautres parties peuvent intercepter ces informations.</li>
<li><a href="https://en.wikipedia.org/wiki/Online_Certificate_Status_Protocol">OCSP wikipedia</a></li>
</ul>
<p>Version openssl : <code class="language-plaintext highlighter-rouge">openssl version</code> → OpenSSL 1.1.1d 10 Sep 2019</p>
<h3 id="lire-un-certificat-avec-un-ocsp">Lire un certificat avec un OCSP</h3>
<p>Nous aurons dabord besoin dun certificat dun site Web. Je vais utiliser xoyize.xyz comme exemple ici. Nous pouvons récupérer le certificat avec la commande openssl suivante:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>openssl s_client -connect xoyize.xyz:443 2&gt;&amp;1 &lt; /dev/null | sed -n '/-----BEGIN/,/-----END/p' &gt; xoyize.xyz.pem
</code></pre></div></div>
<p>Maintenant, vérifiez si ce certificat a un URI OCSP:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>openssl x509 -noout -ocsp_uri -in xoyize.xyz.pem
http://ocsp.int-x3.letsencrypt.org
</code></pre></div></div>
<p>Sil ne donne aucune sortie, le certificat na pas dURI OCSP. Vous ne pouvez pas le valider contre un OCSP.</p>
<h3 id="obtenir-la-chaîne-de-certificats">Obtenir la chaîne de certificats</h3>
<p>Il est nécessaire denvoyer la chaîne de certificats avec le certificat que vous souhaitez valider. Nous devons donc obtenir la chaîne de certificats pour notre domaine, wikipedia.org. En utilisant loption -showcerts avec openssl s_client , nous pouvons voir tous les certificats, y compris la chaîne:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>openssl s_client -connect xoyize.xyz:443 -showcerts 2&gt;&amp;1 &lt; /dev/null
</code></pre></div></div>
<p>Il en résulte une sortie très complète, mais ce qui nous intéresse est ce qui suit</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code> 1 s:C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3
