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!
