You have to read, understand and accept the disclaimer .

You are using ot-unlock-luks at your own risk! There is no guarantee - neither implicitly nor explicitly - given, that using ot-unlock-luks wont affect your system in some negative way.

You are allowed to use ot-unlock-luks to recover access to your personal linux-installation. Commercial use, or using ot-unlock-luks to unlock user-accounts of third-party persons or organizations is explicitly prohibited.

Trying to gain illegal access to third-party computer systems is a serious crime in several countries.

@beta-test version

Be aware: This software is in beta-test at the moment and not being released to public yet; see @beta-test - coverage and Known issues for more details...

About ot-unlock-luks

ot-unlock-luks is used to gain access to a luks encrypted volume via a gui (instead of heaving to use the command line).

You have to know the unlock-password of the luks encrypted volume to be able to access it. (ot-unlock-luks is not a cracking-tool).

ot-unlock-luks should typically be run from a live linux-mint and requires sudo-permission. At a live-mint the predefined user 'mint' does use an 'empty' password = just press 'return', if being asked for the sudo/root password.

Be aware that ot-unlock-luks is referring to specifics of a default linux-mint setup with LUKS encryption and might not work as expected with different linux distros.

Download and run

Download ot-unlock-luks and run it using the preinstalled python - python 2 or python 3 should work both - python3 setups are typically more up-to-date.

Copy/paste the following to a terminal (right-click at the terminal should offer an paste-entry):


# open a terminal and run
cd ~/Downloads
wget https://www.orcus.de/Entities/linux/ot-unlock-luks-001.py
python3 ot-unlock-luks-001.py

		

If you are not using linux mint or wget is not available for some reason use curl instead:


# open a terminal and run
cd ~/Downloads
curl -O https://www.orcus.de/Entities/linux/ot-unlock-luks-001.py
python3 ot-unlock-luks-001.py

		

If ot-unlock-luks is run without root-rights, it offers to reload itself using sudo-credentials. At a live-mint the predefined user 'mint' does use an empty password; press the 'return'-key ('enter'-key) if being asked for a password.

How to use

1) Enter the unlock-password.

If you are using a foreign keyboad layout, you might turn on the 'show cleartext luks pw'-option to proof-read the entered password.

2) Select a luks-encrypted volume.

The default selection is filtered to show only volumes of 'TYPE=crypto_LUKS' (which is the expected value). To see all available volumes, uncheck the 'crypto_LUKS only' checkbox.

3) Use the 'unlock'-button.

After display of a success-message, the button-label will switch to "release".

Keep ot-unlock-luks running and switch to the filemanager, which should offer the decrypted volume now and mount it this way.

When you are done with the decrypted volume, unmount it, using the filemanager, before switching back to ot-unlock-luks.

4) Use the 'release'-button at ot-unlock-luks to finally close the luks-encrypted volume.

After display of a success-message, the button-label will switch back to 'unlock'.

You can close ot-unlock-luks now.

Trouble-shooting

1) Empty volume list

Available volumes are initially filtered to show only volumes with an field TYPE="crypto_LUKS". If you are using a volume with a different TYPE-field: Uncheck the 'crypto_LUKS-only' option button, to show all available volumes.

2) Does not unlock volume

After entering the unlock-password and using the 'unlock' button, the button-label does not change (still showing 'unlock') = the volume cant be unlocked:

You either did select a volume, which does not offer a supported filesystem, or the used password has been invalid. In rare cases a filesystem-error might prevent access.

Select the 'correct' volume and double check your password. Especially if you are not using a EN-US keyboard layout: turn on the 'show cleartext luks pw'-option and check the used luks password.

Broken filesystems cant be accessed without repair. If you suspect a filesystem-error, you might want to check for the output of dmesg at a terminal.

3) Upps - did close ot-unlock-luks before unmounting the volume

Just run ot-unlock-luks again and use the unlock-button (it will ignore that the volume is already unlocked). Afterwards you should be able to release the volume as intended.
