Cryptsetup Lands Support For OPAL Self Encrypting Drives
Linux 6.4 or newer paired with the latest cryptsetup development code has landed support for the OPAL specification for self-encrypting drives.
The OPAL specification is backed by major hardware vendors including Samsung, Micron, SanDisk, Seagate, Hitachi. Toshiba, Kingston, Intel, Lenovo, and others for a self-encrypting drive standard. With code recently merged to the cryptsetup library there is the OPAL bits added. Luca Boccassi commented in the merge request:
"With this I can format, open, use, close and erase multiple partitions on the same SED disk as separate luks volumes, on disks that support Single User Mode and disks that do not. Requires kernel 6.4."
