LUKS/Fedora question: Does anybody know if there is a way to increase the number of passphrase attempts to unlock the encrypted partition at boot before cryptsetup failure ?

#linux #cryptsetup #luks are there any practices surrounding rotating the volume key using `cryptsetup reencrypt <cryptvolume>`?
IIUC, when the header is stolen it is possible to determine exactly which key/passphrase is the correct one. So by exfiltrating the header alone, one could theoretically start cracking. So reencrypting would prevent a stolen header from being useful for too long a long time afterwards.
Granted, it is a bit hypothetical. #security #encryption #confidentiality
My experience with #FlashDrives recently has been mixed. I have no problem in encrypting them with #LUKS, using #cryptsetup or with formatting a partition with #Btrfs, for instance, using #gparted and doing other tinkering with #Gnome #disks. But the problem has been with the actual drives themselves. The cheaper ones seem to have quite a few bad sectors, etc. and so they’re not really reliable for medium term storage.
