       @ParadeGrotesque The use of qcow and qcow2 images is considered to be outdated and flawed by modern cryptography standards.

       @h3artbl33d @ParadeGrotesque Okay, which one is incredibly dense/stupid:  me or the quote?I thought qcow/qcow2 were disk-image formats and had…um…nothing to do with cryptography?

       you're right!  except... it supports a half-ass encryption feature, which is subject to some pretty easy attacks.  usage is explicitly discouraged in the project and has been for a good while now.   I believe but cannot prove that the qcow encryption stuff predates common availability of LUKS and similar full-disk encryption suites in guest OSes.CC: @h3artbl33d@exquisite.social @ParadeGrotesque@mastodon.sdf.org
