Ah I see... yes I used 512 bit key
If 8 512bit keys don't fit in the 1MiB then... wouldn't it make sense to
_generally_ align to 4096S? ... I mean now that we have
cryptsetup-reencrypt (which is awesome by the way)... and people can
(AFAIU) also change their ciphers/modes to something larger?

What a pity... that would have been so awesome ;-)
