cryptsetup-ssh - 2:2.6.1-4~deb12u2 main

Cryptsetup provides an interface for configuring encryption on block
devices (such as /home or swap partitions), using the Linux kernel
device mapper target dm-crypt. It features integrated Linux Unified Key
Setup (LUKS) support.
.
This package provides the cryptsetup-ssh(8) utility and an SSH token plugin
which can be used to unlock LUKS2 devices using a remote keyfile hosted on a
system accessible through SSH. This is currently an *experimental* feature
and mostly serves as a demonstration of the plugin interface API.
