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 managment program
In Linux libata.allow_tpm must be set to 1. Either via 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.
***** sleep (S3) is not supported.
Orginal source code is available on GitHub at https://github.com/Drive-Trust-Alliance/sedutil
Linux and Windows executables and Linux PBA bootloader images for this version of SEDutil are available at https://github.com/ChubbyAnt/sedutil/releases
DTA sedutil: For AMD Ryzen Systems
The sedutil project provides a CLI tool (sedutil-cli) capable of setting up and managing self encrypting drives (SEDs) that comply with the TCG OPAL 2.00 standard. This project also provides a pre-boot authentication image (linuxpba) which can be loaded onto an encrypted disk's shadow MBR. This pre-boot authentication image allows the user enter their password and unlock SED drives during the boot process. Using this tool can make data on the drive inaccessible!
To configure a drive, load a compatible RECOVERY image onto a USB drive and follow the instructions here:
https://github.com/Drive-Trust-Alliance/sedutil/wiki/Encrypting-your-drive
This version of sedutil is based off the original @dta implementation incorporating some modifications by @ladar, @ckamm and @CyrilVanErsche. This fork adds support for the PBA bootloader on AMD Ryzen and AMD Ryzen mobile systems.
Unique to this repo are the following modifications:
- SHA512 password hashing vs SHA1 on original SEDutil
- Compatibile with AMD Ryzen and AMD Ryzen mobile systems
Building is supported on Ubuntu 18.04.3 (LTS) x64. Other versions will probably not compile correctly!
To compile your own version of sedutil you will need the standard development tools, an internet connection, and ~10 GB of disk space.
Prerequisites:
sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install build-essential autoconf pkg-config libc6-dev make g++-multilib m4 libtool ncurses-dev unzip zip git python zlib1g-dev wget bsdmainutils automake curl bc rsync cpio git nasm -y
Automatically Build Everything:
git clone https://github.com/ChubbyAnt/sedutil && cd sedutil && autoreconf --install && ./configure && make all && cd images && ./getresources && ./buildpbaroot && ./buildbios && ./buildUEFI64 && ./buildrescue Rescue32 && ./buildrescue Rescue64 && cd ..
Build Everything Manually Step by Step:
git clone https://github.com/ChubbyAnt/sedutil
cd sedutil
autoreconf --install
./configure
make all
cd images
./getresources
./buildpbaroot
./buildbios
./buildUEFI64
./buildrescue Rescue32
./buildrescue Rescue64
cd ..
The various recovery and boot images will be located in the images directory.
This version has only been verified to boot on a HP x360 Envy AMD 3700u with a Samsung EVO 970 Plus 2TB NVMe drive. Testing has also focused only on the 64 bit UEFI images. While the other variants might work, you should exercise caution, and if possible, test the release on a computer with data that is expendable.
For the most comprehensive information, review this first:
https://github.com/Drive-Trust-Alliance/sedutil/wiki/Encrypting-your-drive
Both the PBA and rescue systems use the us_english keyboard. This can cause issues when setting the password on your normal operating system if you use another keyboard mapping. To make sure the PBA recognizes your password you are encouraged to set up you drive from the rescue system as described on this page.
These are the instructions for modern UEFI NVME equipped systems using SEDutil OPAL locking and unlocking utility as a windows pre-boot bootloader:
Download the rescue system for 64bit UEFI
- UEFI support currently requires that Secure Boot be turned off
Transfer the Rescue image to the USB stick with a program like Balena Etcher.
Restart your computer, enter the BIOS, and disable secure boot.
Note: Earlier versions of SEDutil also required BIOS enable of "legacy boot" or "CSM" or "Compatility Mode" - this is no longer required with this version of SEDutil.
Boot the USB thumb drive with the rescue system on it. You will see the Login prompt, enter "root" there is no password so you will get a root shell prompt.
enter the command sedutil-cli --scan

Verify that your drive has a 2 in the second column indicating OPAL 2 support. If it doesn't do not proceed, there is something that is preventing sedutil from supporting your drive. If you continue you may erase all of your data.
Enter the command linuxpba and use a pass-phrase of debug. If you don't use debug as the pass-phrase your system will reboot!

Verify that Your drive is listed and the that the PBA reports it as "is OPAL"
Issuing the commands in the steps that follow will enable OPAL locking. If you have a problem you will need to follow the steps at the end of this page Recovery Information to either disable or remove OPAL locking.
The following steps use /dev/nvme0 as the device and UEFI64-1.15.img.gz for the PBA image, substitute the proper /dev/nvme? for your drive and the proper PBA name for your system
#Enable Locking and the PBA

#Your drive in now using OPAL locking.
You now need to COMPLETELY POWER DOWN YOUR SYSTEM
This will lock the drive so that when you restart your system it will boot the PBA.
#Recovery information:
If there is an issue after enabling locking you can either disable locking or remove OPAL to continue using your drive without locking.
If you want to disable Locking and the PBA:
sedutil-cli -–disableLockingRange 0 <password> <drive>
sedutil-cli –-setMBREnable off <password> <drive>
Expected Output:
#sedutil-cli --disablelockingrange 0 debug /dev/nvme0
- 14:07:24.914 INFO: LockingRange0 disabled
#sedutil-cli --setmbrenable off debug /dev/nvme0
- 14:08:21.999 INFO: MBREnable set off
You can re-enable locking and the PBA using this command sequence:
sedutil-cli -–enableLockingRange 0 <password> <drive>
sedutil-cli –-setMBREnable on <password> <drive>
Expected Output:
#sedutil-cli --enablelockingrange 0 debug /dev/nvme0
- 14:07:24.914 INFO: LockingRange0 enabled ReadLocking,WriteLocking
#sedutil-cli --setmbrenable on debug /dev/nvme0
- 14:08:21.999 INFO: MBREnable set on
Some OPAL drives have a firmware bug that will erase all of your data if you issue the commands below. See Remove OPAL for a list of drive/firmware pairs that is know to have been tested.
#To remove OPAL issue these commands:
sedutil-cli --revertnoerase <password> <drive>
Expected Output:
#sedutil-cli --revertnoerase debug /dev/nvme0
- 14:22:47.060 INFO: Revert LockingSP complete
Verify that the locking SP has been deactivated:
sedutil-cli --query {drive}
Look at the query output and make certain that the Locking section shows lockingEnabled=N
-----
Locking function (0x0002)
Locked = N, LockingEnabled = N, LockingSupported = Y,
---------
If the query does not show lockingEnabled=N DO NOT CONTINUE with the next step, if you do all your data will be erased.
Remove OPAL:
sedutil-cli --reverttper {SIDpassword} {drive}
Expected output:
#sedutil-cli --reverttper debug /dev/nvme0
- 14:23:13.968 INFO: revertTper completed successfully
#
When this is finished the drive will be in a non-opal managed state. This would allow you to do anything that you could have done before starting OPAL management under OPAL. You can also reinitiate OPAL management if you wish.
