[ENCRYPTION] Bitlocker drive question

[vr000m]

I upgraded 20.04 to 22.04 and I was pleasantly surprised to see that dolphin now recognizes a bitlocker encrypted drive and also mounts it.

I am wondering how I can do that from the command line in 22.04 LTS.

TIA.

[vr000m]

cryptsetup bitlkOpen /dev/sdb bitlocker
Enter passphrase for /dev/sdb:<passphrase><Enter>
This creates a new entry under /dev/mapper. In my case it created "bitlocker" that is a link to "../dm-3".
mount /dev/mapper/bitlocker /media/<my mount point>

This does the trick.

it should be the same no matter the distro, so I imagine this will work:

If you want to use the same directory as Dolphin you can use the file manager to see full path to where it is mounted.

I have no experience with bitlocker so other than basics, i have no idea how this works in the real world.

I don't think dislocker has anything to do with it. I feel that bitlocker file system support is added to kernel now. 22.04 uses 5.15 so it was added sometime before then. I never got dislocker to work even after following all the instructions on the github site.

I was using hasleo's version of dislocker which worked for me but everytime there is even a minor update, I had to re-install their s/w and that was very frequent. It now seems integrated so that all I have to do in the file manager is enter the passphrase.

I want to be able to mount it from command line for various different use cases, including on a server installation where there isn't any X running.

Well, just the mounting procedure will be done essentially the same way it is for manually mouinting any drive:

So use Step 4 on the tutorial:

sudo dislocker <partition> -u<password> -- /media/bitlocker

sudo mount -o loop /media/bitlocker/dislocker-file /media/bitlockermount

if there is a different tool or command to decrypt the partition, just substitute that in the first line.

I don't think that the Hasleo Disklocker has any relation to the command line Linux tool dislocker. I am going to guess that the Linux command line tool now has kio or FUSE integration available to allow it to be used by various file managers.

I was probably not clear. I do NOT have dislocker installed anymore. I gave up on that long ago as it failed to work for me.
Kubuntu 22.04 simply mounts bitlocker encrypted usb device in dolphin after a password input, just as in windows file manager.
I do not know what is done under the cover hence this post.

Sorry, I did not understand this. Apologies.

I have no idea what application is being used under the hood to decrypt bitlocker, and don't see any relevant info on the topic so far. The process to decrypt and mount will be the same exact method as I have shown, just needing to discover what application/command is being used to do so. It likely is not at all related to KDE specifically. I am wondering if the tools to encrypt/decrypt Linux disk encryption (LUKS, etc) are now able to do so for bitlocker.

I am hoping someone who uses this feature can chime in.
it would be easy if I had a Windows install to test this on, but I am completely WIndows free right now.

Awesome!!!

Glad you discovered this. I am sure others will find it useful.
