I successfully re-installed Ubuntu with the built-in encryption on, and now I need
to do _something like_ letting my employer verify that I do have it encrypted.
I say  "something like"  because, _for built-in encryption_,
submitting a screenshot would be enough.
However, I have not found any way of

(a)  taking a screenshot of the  "Please unlock disk"  screen
or
(b)  bringing up anything else showing that the built-in encryption is enabled



Simplest is:



sudo blkid /dev/YourDiskPartition...

Result should contain: TYPE="crypto_LUKS"

And your boss should know enough to understand what it means...

I dare to disagree :)

That line only shows, that somewhere LUKS is being used.

In 99% of possible installments, that's not enough:  far too simple pwd, multiple OS'es....
So those line ar at best misleading.

And "your boss should know..": come on, you're joking!
