List open dm-crypt LUKS volumes

Question

If I mount a simple loop device,

losetup -a

give me the devices opened. Is something similar possible with cryptsetup?

dmsetup is useful for anything device mapper related. For Example:

[root@localhost]~# dmsetup ls --target crypt
luks-90dc732d-e183-4948-951e-c32f3f11b305   (253, 0)
[root@localhost]~#

Is there any way to list all mappings with their target type? The best I could manage was for i in $(sudo dmsetup targets | cut -f1 -d' '); do echo $i:; sudo dmsetup ls --target $i; echo; done – mwfearnley Apr 5 '18 at 9:49

Thx. Getting the list shouldn't be so cryptic... luksList would be nice. – bvj Apr 18 '19 at 5:31

I just looked for the same thing, a list of my luks partitions, though I wanted a mapping to the physical /dev/sdX devices.

lsblk --fs
