sedutil - The Drive Trust Alliance Self Encrypting Drive Utility
This program and it's accompanying Pre-Boot Authorization image allow you to enable the locking in SED's that comply with the TCG OPAL 2.00 standard on bios machines.
You must be administrator/root to run the host management program
In Linux libata.allow_tpm must be set to 1 for SATA-based drives, including NGFF/M.2 SATA drives.Either adding libata.allow_tpm=1 to the kernel flags at boot time or changing the contents of /sys/module/libata/parameters/allow_tpm from a "0" to a "1" on a running system if possible will accomplish this. NVMe drives do not need this parameter.
This version supports S3-Sleep (suspend to RAM) for convenience, which gives the sleeping kernel the hash of the password to resume. This is less secure than S4-Hibernation (suspend to disk), which will reboot the computer and start the PBA again.
Custom password hashing functions can also be chosen at runtime, with support for all known forks (DTA, ladar, ChubbyAnt, badicsalex and Ralayax). ChubbyAnt's preset is used by default as it offers better security than the official DTA preset and appears to have been used a lot.
