How do I make kali live run on a full encripted pendrive?

[Regis]

I have already configured GRUB2 to request the /dev/sdb disk encryption password and read the /boot folder:

I added the root = 'crypto0' entry in grub.cfg.
crypto0 is the device that grub rides after decrypting.

set root='crypto0'
linux    /live/vmlinuz-4.19.0-kali3-amd64 boot=live components splash username=root hostname=kali
initrd   /live/initrd.img-4.19.0-kali3-amd64

But the kernel load stops loading and displays the following error:

"Unable to find a medium containing a live file system"

I want to use my pendrive with kali live without anyone knowing what's inside, absolutely nothing!
Has anyone tried something like this and managed to make it work?
