The PHDR is 592 bytes, but the keyslot sizes depend on the number of AFstrips and the keysize. If one us using AES-256 with XTS and 4000 strips, then the space LUKS takes up will be around 2 megabytes. --------------------------------------------------------------------- dm-crypt mailing list - http://www.saout.de/misc/dm-crypt/ To unsubscribe, e-mail: dm-crypt-unsubscribe@xxxxxxxx For additional commands, e-mail: dm-crypt-help@xxxxxxxx
