Subject: [dm-crypt] length of keyfiles
Date: Wed, 06 Jan 2021 10:17:22 +0100 [thread overview]
Message-ID: <b2f9f2aa1134d54b1d08cabfb275e0bc@kngnt.org> (raw)
Hi everybody,
I have seen that keyfiles can be used in cryptsetup up to 8 kB, but
internally the master key is 512 bits at max. Is there any
recommendation / increased security by using a random sequence of 8 kB
w.r.t., let's say, one of just 64 bytes?
I understand that using one of 8kB will require more time than one of 64
B when unlocking the volume, but... is the former really that much more
secure than the latter?
Regards!
Felix
