Data Security Technologies TCG Opal 2. The Opal SSC, currently available in version 2. What are Opal 2. Self-encrypting drives SEDs supporting Opal 2. By encrypting the entire drive, users do not have to worry about their data being accessed if the drive, laptop or mobile device gets stolen or lost.

Upon power on, the user supplies a password, passphrase or other authentication mechanism, from which the host application generates an Authentication Credential. This credential is then sent to the SED to unlock the drive and provide access to the data. Advantages of Opal 2. These SEDs offer several benefits and advantages over software-based encryption:.

Figure 2. Security Features. Opal 2. An Opal-compliant SED offers several advantages in effectively preventing unauthorized data access due to the loss or theft of the drive or a system that integrates the drive. However, it is not designed to protect data from a breach that occurs after the drive has been unlocked with valid authentication credentials with the OS and applications already launched. If the authorized user has not yet been de-authenticated by the system through a power cycle, the drive remains vulnerable and therefore requires other security mechanisms to keep it protected from unauthorized access.

ATP SecurStor provides a multi-level security suite that protects data with a variety of options beyond data-at-rest encryption and pre-boot authentication. Customers can choose from features that can be customized according to their application-specific requirements to guard against unauthorized access, illegal copying and other security threats to ensure data, OS and firmware integrity at all times.

This password stayed with the drive so decrypting still required entry of the password if the drive were removed from the system.

There is no option for a drive password in BIOS and hence nothing to enter prior to boot, unless I put in a system password.

I assume that the data is encrypted on the drive, but am not sure that the data would be inaccessible if the drive were removed from the Is the encryption tied to the specific system so the drive is unusable elsewhere? I've done some searching but can't seem to locate definitive information about this particular type of SED.

Go to Solution. The KB article about that is here. If you want to take advantage of encryption, you may want to consider BitLocker if you have a Pro version of Windows, or VeraCrypt if you don't. The latter may introduce some extra complications if you're on Windows 10 since Microsoft will be pushing a new release every 6 months and they obviously don't officially support VeraCrypt, whereas BitLocker is Microsoft's own solution.

It's also typically easier to recover drives protected with software encryption in another PC. With Class 0 encryption, you need to install it internally into another system that knows how to prompt for an HDD password, whereas with software encryption you can connect the drive through an external enclosure and access it just fine that way, no "hardware-level unlock" support required. Granted, NVMe enclosures are still quite expensive, so for the time being that particular advantage is more relevant for SATA drives, but NVMe enclsoures will likely become more common in the future.

View solution in original post. I wanted to know, if there is an instruction how to get Windows 10 with Bitlocker to use the hardware encryption of the drive.

I tried to enable Bitlocker, which worked, but it uses software encryption. There isn't usually an easy way to do this. The drive has to be prepped before you even run Windows Setup. For Samsung retail SSDs, their recommended process is to install Windows just to run Samsung Magician for this purpose, and then choose to prep the drive.

Convenient, right? Dell, could it please be up to us, the users, to decide wether we want to use Class0 passwords on NVMe devices or not? In other words: I want to use hardware-based encryption. And I not only want to use it for performance reasons but also to increase reliability whereas software tends to have bugs, updates, security issues, etc.

On top of that, it again uses software for unlocking the device. Linux and Windows. I've used hardware based encryption for so many years now via SSD ATA password and I still think that it is the best solution in terms of usability and even security even when proprietary. And I think that usability and security go hand in hand when it comes to the question if users enable encryption or not.

At the time of my purchase, Dell offered no comparable drive via the store. For TCG Opal you can activate encryption via some third party specific software. Software encryption is old and is from far away beated by hardware encryption. Driver Trust sollutions uses a small shadow partition few mb, where is running a small linux which activate the hardware encryption.

The utilities and software along with instructiona are available for free on github. If you have multiple ssd encrypted inside the same pc you cannot decrypt them from boot. It has a pretty nice gui interface before boot. After reboot or shutdown the drives are ofcorse encrypted back.

They are very quick and very helpful with technical support. It depends of windows version and can give you errors sometines but with the help of technical stuff from vendor everything worked in the end.

I personally recommend if you are a home user using tcg opal emcryption with the software from Driver Trust for one single ssd. For more ssd in the same pc i recommend WinMagic SecureDoc.The Opal Storage Specification is a set of specifications for features of data storage devices such as disk drives that enhance their security.

For example, it defines a way of encrypting the stored data so that an unauthorized person who gains possession of the device cannot see the data. That is, it is a specification for self-encrypting drives SED. Radboud University researchers indicated in November that some hardware encryption, including some Opal implementations, had security vulnerabilities. From Wikipedia, the free encyclopedia.

I see no way of setting if it is bit or bit. I am confident I do not understand this fully but I am trying to. Is this the case or am I living in a false sense of security? Also, and this might seem dumb, if I put the drive in another compatible ThinkPad that I have a Supervisor password set on that does not mean I am able to overwrite the Hard Disk password I would hope? What I mean is if I forget the Hard Disk password then I am screwed when it comes to getting the data back?

Also as a final question I would like to know how one would regenerate a new DEK on the drive? I have seen mention in some Lenovo Support docs that there should be an BIOS option in Security to reset the encryption key but I cannot find such an option.

Yet it mentions "data" and not being accessible if the key is cleared. I would like to at least know the process of regenerating a new DEK.

So I selected to 'Turn on BitLocker' and it told me the drive was already encrypted so it just needed to be 'activated'. I did that and it was instant. Then I decided to see what would happen if I turned BitLocker off. Interestingly it didn't just say it would be deactivated but instead it actually went through the normal process of decrypting the drive!? Now when I do a manage-bde -status it reports it is not encrypted?!

Is BitLocker not identifying things quite right or is something else going on? Is it even possible to select between and bit AES for drives encryption? If so how is this done?

It does not appear to do anything other than add the padlock to the drive icon in File Explorer. Maybe I am missing some management benefits it brings?

The way I see things is that using the BIOS Hard disk password is a nice option for a single user like myself as I can manage the password and I don't need any third-party software like sedutil or WinMagic. My question is do I actually need to have RST installed? I never bothered with it as I figured it was not needed with an NVMe drive but was wondering if it is used for anything else?

With either method, the encryption is exactly the same. If you look in the RST driver readme, it should say this.

Supervisor password and HDD password are not related at all. The link you gave me to the encryption key reset tool is from and does not specify the X1C6 20KH, 20KG as supported models.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Work fast with our official CLI.

If nothing happens, download the GitHub extension for Visual Studio and try again. Also allows saving password in the running kernel for S3 Sleep support, cause it was a cheap feature to have. Based on Kyle Manna's opalctl nano-utility.

If you need to use older kernel, checkout v0. If you are Gentoo Linux user, you will find an ebuild in my overlay. When the disk has been initialized with sedutil-cli without using its -n option, the password which is send to the disk is a hash calculated using PKBDF2 algorithm from plain text password and the disk serial for salting.

In order to use such password with sed-opal-unlockerall you need to do is to store the hashed password in the password file. Fortunately, there's a Python script which will do this for you.

You need to call this script once, as root, cause it reads serial number from the disk needed to salt the password for hashing. Plaintext disk password is entered on script standard input. Hashed password with some magic value for file type recognition is written to the output file specified by second argument. Note that the file will be overwritten when it exists. The unlock passphrase can be optionally salted with current machine's DMI data serial number or UUIDwhich makes it usable only on this machine.

This can be hacked around of course, but attacker needs to know this data cause it's not stored in the encrypted password file. When an encrypted password file is provided to sed-opal-unlocker, it will ask for the unlock passphrase on stdin. Note that password encryption currently cannot be used when disk has been initialized without password hashing sedutil -n. Even having access to the disk does not make bruteforcing easier, cause a argon2, b OPAL disks have limit how many times you may enter wrong password, and then will require a power-cycle to start talking to you again.

The most helpful information source for me was Self-Encrypting Drives article on Archlinux wiki. Another source worth looking at is sedutil wiki. Despite I'm encrypting non-root secondary disk, I still prefer to enable MBR shadowing and filling it with zeros.

Otherwise when kernel boots and tries to read partition table while the disk is still locked, scary looking IO errors are generated, and disk also saves them in some SMART error counter.

Please note that tinkering with your drive may cause data loss. It's best to work with an empty drive, so you lose nothing when screwing up. Do not execute this for your root drive.

Silicon Power

It won't boot without a proper PBA image. Non-indented line represents command to be executed, following indented lines are its example output. Copying takes a while and it's better not to interrupt it - disk may hang, stop responding and require a power-cycle to recover.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. I have a fresh install of Ubuntu As far as I understand, the drive is always encrypted, but I need to set a password so that the encrytion key itself is also protected.

You are correct in that the encryption is always on.

TCG Opal 2.0

The data will automatically be decrypted once the system is booted. The keys that perform the encryption and decryption for the drive are embedded on a chip in the hardware itself.

The secondary ATA password provides an additional level of security. Be aware that if that secondary password is lost, data recovery will be impossible. Many self-encrypting drive producers provide software tools to enable users to create this additional password.

If you are interested the specification is here. It also seems that sometimes other drives, such as the Seagate Pro SSD, are used; so it's important when using Windows to know which drive is being used so you can visit the manufacturer's website.

Once you install a custom operating system you need to use the tools available for that OS.

PROTECT YOUR DATA! Use an Intel SSD with Full Disk Encryption NCIX Tech Tips

Samsung SSDs have software available to setup their operation, this only works for certain SSDs and operating systems, otherwise the default is no password and encryption is enabled. For "Ubuntu Using a bootable USB drive with Windows and Samsung's Windows software is another, albeit inconvenient, option for setting up your SSD for use with another operating system.

Don't forget to set your screensaver to a short time and hibernation should also be brief if you want the encrypted drive to remain secure, see my other answer linked to above, a powered on encrypted drive is unlocked once it's successfully booted. On Linux distributions, a low-level utility sedutil-cli is available to provision and administrate Opal 2 drives. However, it is rather difficult to use directly.

The PBA's provided along with sedutil-cli do not support international keyboard layouts or Secure Boot.Nordic Visitor was one of the best travel decisions I've ever made.

They made everything so easy, while giving us the freedom of being able to 'adventure' on our own. Our itinerary and maps were comprehensive, with many personal touches from Thordis, our travel agent. I hope to book another trip with Nordic Visitor again soon. Helena was one of the best travel consultants I have ever worked with. She quickly answered all questions and was a delight to work with. We just returned from our trip and we wanted to tell you thank you. Everything you planned was wonderful.

We loved the tours in Kiruna, especially the dog sledding. The ice hotel was amazing and we loved the room you picked for us. The hotels you picked were very nice and we never would have found them on our own.

We liked the Hurtigruten and were so happy when we got to see the Northern lights on the deck on the second night. We even enjoyed the bus and train rides because the scenery was so beautiful. The guides in Kiruna were especially nice and helped us locate a piece of luggage we lost while we were on a tour so we could make our train on time afterward. Amazing trip, from airport pick-up to drop-off.

Alexandra was amazingly helpful. Your country is wonderful. Just wish we had seen the Lights. It was a pleasure to deal with Cecilia Markov. The overall trip experience for us (Two couples) was memorable.

The ferry trip to Flam, the stay and dinner at Fretheim Hotel were outstanding. The Flam railway train ride was sensational and so was the train journey back to Oslo. We found the people kangaro stapler repair Norway, friendly and helpful.

The whole country is beautiful. The city of Oslo was a delight to explore. We would gladly come back again for a holiday in Norway.
