Cryptsetup cipher

WebUse cryptsetup --help to show the defaults. --cipher, -c Set the cipher specification string. cryptsetup --help shows the compiled-in defaults. The current default in the distributed sources is "aes-cbc-essiv:sha256" for both plain dm-crypt and LUKS. WebSet the cipher specification string. cryptsetup --help shows the compiled-in defaults. If a hash is part of the cipher specification, then it is used as part of the IV generation. For example, ESSIV needs a hash function, while "plain64" does not and hence none is specified.
