cryptsetup-ssh 2:2.6.1-1ubuntu1 (s390x binary) in ubuntu lunar

 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.
