Edd<p>After a request on the <a href="https://mastodon.eddmil.es/tags/selfhosted" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>selfhosted</span></a> community on Lemmy, I wrote up how I use LUKS, Clevis, and Tang to give me network-bound encryption. This means that I can restart my servers as long as they're on my home network without worrying about having to log in to decrypt the drive, but if someone breaks in and steals my servers and turns them on anywhere else, the data on them is safe. <a href="https://i.am.eddmil.es/clevistang/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="">i.am.eddmil.es/clevistang/</span><span class="invisible"></span></a></p><p><a href="https://mastodon.eddmil.es/tags/selfhosting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>selfhosting</span></a> <a href="https://mastodon.eddmil.es/tags/encryption" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>encryption</span></a> <a href="https://mastodon.eddmil.es/tags/LUKS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LUKS</span></a> <a href="https://mastodon.eddmil.es/tags/clevis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>clevis</span></a> <a href="https://mastodon.eddmil.es/tags/tang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>tang</span></a></p>
