Cant Find the Luks_key when I finished the disk encryption

When i finished the disk encryption(about the encryption flow u can see in the topic disk encryption) and try to test the function.We have the worst experience ever with your documentation.
First,I umount the mountpoint and close the mapper. Then i try to open the mapper again . It shows that I need a password and I know it’s the luks_key but I dont know how to get it .


I had used the bash but the nvluks_srv_app return “00000000000000000000000000000000”

If there has any detail i ignored ,plese help me thanks.

Please share steps so that we can set up and test to reproduce the issue. And do you use latest Jetpack 4.6.1?

thanks for u response
yes i did the lastest jetpack4.6.1
and if u want the step how i encrypt the disk can be seen in this topic disk encryption .I have encrypted disk successfully .
The following steps are using to test if the encryted disk can be mounted
1.boot and check the disk

hg@hg-desktop:~$ lsblk
hg@hg-desktop:~$ df -h

2.umount the crypt_UDA and close the mapper

hg@hg-desktop:~$ sudo umount /mnt/crypt_UDA
hg@hg-desktop:~$ sudo ccryptsetup close crypt_UDA

3.test open new mapper

hg@hg-desktop:~$ sudo cryptsetup open /dev/mmcblk0p43 test

I need enter passphrase for /dev/mmcblk0p43 . If this passphrase is the luks_key and what is the key .
i find the doc saying to unlock encrypted disk

if the nvluks-srv-app is used to get the passphrase.i try it

hg@hg-desktop:~$ sudo nvluks-srv-app --context-string "UUID" --get-unique-pass

why all zero ? i cant use it to unlock the disk.

If Nvidia has some testing doc to teach us if a disk is encrypted.thanks so much

There is guidance in developer guide Have you checked the section?

yes,i follow the guidance finished the disk encryption.
BUT,now i want to test the encryption with no guidance
