I just recently created a Kali (2019.1) Live USB device, disabled secure boot on my HP Spectre x360 laptop and fired it up. I've referred to both of the following guides, but they all a refer to a separate persistence partition to be saved on:


Is it possible to enable USB Encrypted Persistence with a single partition on my USB flash drive. It's currently listed as /dev/sda1

Code:
File system:  fat32
Label:  KALI_LIVE-2
Used:  3.27 GiB  (11%)
Unused:  25.37 GiB  (89%)
Size:  28.64 GiB
Status:  Mounted on /run/live/medium, /usr/lib/live/mount/medium
If it's not possible, can I use GParted or some other built in Kali tool to make adjustments to the partition and maybe set up a ~20GB Encrypted Persistence partition for usage? Thanks for any assistance to my little dilemma. It's been a while since i've actually used Kali... in fact, the last time I had a USB flash drive I carried around with me was in the Backtrack Linux days, for cracking WEP. Have a lot to learn.
