is it possible to get or how can i create a volume with an invalid key? i
would lik3 to test this for my program zulucrypt but i cant seem to manage
to corrupt a volume. The best i have got after trying for hours is
inconsistency at best.

crypt_keyslot_status API shows the key is invalid but cryptsetup luksDump
shown the key slot as disabled and cryptsetup executable just says the
password does not exist when trying to open the volume with the a key in
slot i try to make invalid
