Cryptsetup cipher
WebThis master key gets decrypted with one of the keys in your key slots when you boot/open the device (try cryptsetup luksDump /dev/sdx to see information contained in the LUKS header). When you first format the LUKS device, it will ask you for a passphrase (or keyfile). Websudo cryptsetup luksFormat --cipher aes-cbc-essiv:sha256 --key-size 256 --iter-time 2100 --hash sha512 /dev/loop0 But if the device already exists, how can I change for example sha256 to sha1 or change the iteration time without "destroying" the device. (Clearly you would have to retype your password since a new hash will be generated.) luks
