WebMar 8, 2024 · Cryptsetup provides an interface for configuring encryption on block devices (such as /home or swap partitions), using the Linux kernel device mapper target dm-crypt. It features integrated Linux Unified Key Setup (LUKS) support. This package provides the cryptsetup, integritysetup and veritysetup utilities. Installed size: 2.27 MB. WebLRW: The Liskov-Rivest-Wagner tweakable narrow-block mode, a mode of operation specifically designed for disk encryption. Superseded by the more secure XTS mode due to security concerns. [124] XTS: XEX-based Tweaked CodeBook mode (TCB) with CipherText Stealing (CTS), the SISWG (IEEE P1619) standard for disk encryption.

Webcryptsetup --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. For XTS mode you can optionally set a key size of 512 bits with the -s option.
