Linux 5.9 To Support DM-CRYPT On Zoned Block Devices | Tux The Linux Device Manager's dm-crypt allows for transparent disk encryption and does so quite well, but until now hasn't properly supported zoned block devices. Login … EXT4 fscrypt vs. eCryptfs vs. LUKS dm-crypt Benchmarks The options tested were EXT4, fscrypt, eCryptfs, and LUKS dm-crypt encryption with the EXT4 file-system and tested with the defaults unless otherwise noted. A Toshiba TR150 SATA 3.0 SSD was used as the drive under test for all of the benchmarking. Ubuntu 18.04 LTS was the basis for this benchmarking aside from the Linux kernel upgrade.
Encrypting block devices using dm-crypt/LUKS. Linux Unified Key Setup (LUKS) is a specification for block device encryption. It establishes an on-disk format for the data, as well as a passphrase/key management policy. LUKS uses the kernel device mapper subsystem via the dm-crypt module. This arrangement provides a low-level mapping that handles encryption and decryption of the device's data.
