Démonter le répertoire :<br />
<code class="language-plaintext highlighter-rouge">ecryptfs-umount-private</code></p>
<h3 id="montage-auto-pam">Montage Auto (PAM)</h3>
<p>Le montage d’une partition chiffrée à l’ouverture de session est fait à l’aide de <strong>PAM</strong> voir <strong>/usr/share/doc/ecryptfs-utils/README</strong> et le module doit être chargé (sudo modprobe ecryptfs)</p>
<h4 id="configuration-pam">Configuration PAM</h4>
<p>1- Vérifier ou créer (touch) les fichiers <strong>~/.ecryptfs/auto-mount</strong>, <strong>~/.ecryptfs/auto-umount</strong> et <strong>~/.ecryptfs/wrapped-passphrase</strong> (créer avec utilitaire <strong>ecryptfs-setup-private</strong>).</p>
<p>2- Ajouter <strong>ecryptfs</strong> au pam exactement comme ce qui suit pour que la <strong>login passphrase</strong> ne soit plus demandée :<br />
Ouvrir <strong>/etc/pam.d/system-auth</strong></p>
<p><strong>APRES</strong> la ligne contenant <code class="language-plaintext highlighter-rouge">auth required pam_unix.so</code> (ou <code class="language-plaintext highlighter-rouge">auth [default=die] pam_faillock.so authfail</code> si présent) ajouter:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>auth [success=1 default=ignore] pam_succeed_if.so service = systemd-user quiet
auth required pam_ecryptfs.so unwrap
</code></pre></div></div>
<p>Ensuite, <strong>AU-DESSUS</strong> de la ligne contenant <code class="language-plaintext highlighter-rouge">password required pam_unix.so</code> (or <code class="language-plaintext highlighter-rouge">-password [success=1 default=ignore] pam_systemd_home.so</code> si présent) insérer:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>password optional pam_ecryptfs.so
</code></pre></div></div>
<p>Et finalement <strong>APRES</strong> la ligne <code class="language-plaintext highlighter-rouge">session required pam_unix.so</code> ajouter:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>session [success=1 default=ignore] pam_succeed_if.so service = systemd-user quiet
session optional pam_ecryptfs.so unwrap
</code></pre></div></div>
<p><img src="/images/ecryptfs-pam.png" alt="" /></p>
<p class="info"><strong>Note</strong> : Les instructions <code class="language-plaintext highlighter-rouge">pam_succeed_if.so</code> indiquent au processus de sauter la ligne suivante si le service demandant l’authentification est <code class="language-plaintext highlighter-rouge">systemd-user</code>, qui fonctionne parallèlement à votre session utilisateur et s’authentifie également via PAM. Si le répertoire personnel est monté une deuxième fois, PAM sera incapable de le démonter. Ceci est référencé comme une rupture avec systemd. La méthode exposée ici est une solution de contournement.</p>
<p>3- Sauvegarde , déconnexion ,reconnexion et vérifier la sortie du mount</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>mount
</code></pre></div></div>
<p>qui devrait maintenant contenir un point de montage, par exemple:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>/home/$USER/.Private on /home/$USER/Private type ecryptfs (...)
</code></pre></div></div>
<p>pour le répertoire crypté de l’utilisateur. Il doit être parfaitement lisible sur <strong>~$HOME/Private/</strong></p>
<h2 id="modification-mot-de-passe">Modification mot de passe</h2>
<p>Si vous avez modifié votre mot de passe depuis la ligne de commande à l’aide “passwd”, le système ecryptfs ne vous autorisera plus à accéder aux données chiffrées.<br />
Votre dossier chiffré est devenu illisible et non-déchiffrable parce que le montage du dossier ecryptfs est basé sur votre ancien mot de passe.<br />
Vous pouvez vous en tirer si vous connaissez la passphrase mais vous n’avez aucune solution dans le cas contraire.</p>
<h3 id="accés-temporaire">accés temporaire</h3>
<p>Pour accéder aux données, il faut monter le dossier chiffré manuellement</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo mount -t ecryptfs ~/.Private ~/Private -o key=passphrase,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_passthrough=n
</code></pre></div></div>
<p>La passphrase vous sera demandée et le dossier Private sera monté correctement.</p>
<h3 id="rétablir-un-fonctionnement-normal">rétablir un fonctionnement normal</h3>
<p>Si vous avez modifié votre mot de passe depuis la ligne de commande, vous remarquerez que la passphrase utilisée pour monter votre dossier personnel chiffré n’est PAS mise à jour. Ceci évite qu’un super utilisateur (ex. : root) puisse accéder à vos données simplement en modifiant votre mot de passe d’utilisateur et en se connectant avec votre identifiant.</p>
<p>Afin de modifier votre passphrase Ecryptfs (pour qu’elle coïncide avec votre nouveau mot de passe), utilisez cette commande :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ecryptfs-rewrap-passphrase ~/.ecryptfs/wrapped-passphrase
</code></pre></div></div>
<p>Vous devrez saisir votre ancienne passphrase, puis la nouvelle.</p>
<p>Vous pourrez alors utiliser votre répertoire crypté normalement.\</p>
