Baffled About Passphrases

[Ron Allen Smith]

Hi,

I'm new to Qubes/Linux and would like to know how to change/add/remove
passphrases applied to the USB I installed Qubes 3.2 on. I looked around
at Qubes FAQs and elsewhere, which was helpful, but not giving a
step-by-step of what to do.

[user@untrusted ~]$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvdc 202:32 1 11.5G 0 disk
├─xvdc2 202:34 1 10.5G 0 part
│ └─dmroot 253:0 0 10G 0 dm /
└─xvdc1 202:33 1 1G 0 part [SWAP]
xvda 202:0 1 10G 1 disk
└─dmroot 253:0 0 10G 0 dm /
xvdd 202:48 1 500M 1 disk
/usr/lib/modules/4.9.56-21.pvops.qubes.x86_64
xvdb 202:16 1 2G 0 disk /rw

Although I selected default encryption during the Qubes install, I can't
determine whether or not enryption is actually set.

I also looked at 'man cryptsetup', but unsure of how to use it, or even
if I should use it.

Can anyone set me on the right path?
