Subject: [dm-crypt] How to compress LUKS v2 header?
Date: Thu, 26 Dec 2019 20:20:44 +0000 [thread overview]
Message-ID: <fbd7b3b7e45a48d7896cb3b644fd86bb@br.ibm.com> (raw)
Hi all,
I'm trying to compress a LUKS v2 header file, but I'm not seeing any
sensible reduction.
I'm using `cryptsetup luksHeaderBackup /dev/sda2 --header-backup-file /tmp/backup.header`
I used ZIP and GZIP, but I got 0% of reduction of `backup.header`. :-(
Do you have any suggestions of what algorithm should be used to
compress this type of file?
Thanks!
