Why can Bitlocker be automatically identified

I have a problem that I don’t need to solve. I want to know why my Manjaro can identify the U disk after the Bitlocker encrypted? I did n’t install Dislocker or other similar tools, it ’s strange! Is it because my computer is a problem? The corresponding driver of Bitlocker? Or is it because of Manjaro’s built -in software?

What do you mean?

Why can it see that it is a bitlocker device?

Or are you saying it can be decrypted as well?

Do you have cryptsetup or something similar?

Because the U disk is the U disk - encryption with bitlocker or luks does not change the disk only the content.
