<h2 id="chiffrer-un-disque-dur-externe-ou-une-clé-usb-avec-dm-crypt--luks">Chiffrer un disque dur externe (ou une clé USB) avec dm-crypt &amp; LUKS</h2>
<ul>
<li><strong>LUKS</strong> pour Linux Unified Key Setup est une norme de chiffrement de disque. On peut lutiliser pour chiffrer une ou plusieurs partition et ainsi améliorer la sécurité de son système.</li>
<li>dm-crypt est le système utilisé par le noyau Linux pour la gestion des clefs et des disques. Son utilitaire cryptsetup permet de gérer les disques au format LUKS. <u>L'on parle donc de dm-crypt avec LUKS, habituellement simplifié à juste "LUKS".</u></li>
</ul>
<p><a href="http://doc.ubuntu-fr.org/cryptsetup">Partition chiffrée avec Cryptsetup</a> .<em>Afin de protéger au mieux vos données personnelles, il peut être nécessaire de chiffrer vos partitions utilisateur. En effet, si via le système il est impossible daccéder aux fichiers qui ne vous appartiennent pas, un simple passage sur un livecd permet daccéder à nimporte quel fichier de votre système. Le chiffrement de partition avec <strong>Cryptsetup</strong> permet déviter ça.</em></p>
<p><em><strong>LUKS</strong> permet de chiffrer lintégralité dun disque de telle sorte que celui-ci soit utilisable sur dautres plates-formes et distributions de Linux (voire dautres systèmes dexploitation). Il supporte des mots de passe multiples, afin que plusieurs utilisateurs soient en mesure de déchiffrer le même volume sans partager leur mot de passe.</em></p>
