systemd-cryptsetup [at] .service
systemd-cryptsetup [at] .service is a service responsible for setting up encrypted block devices. It is instantiated for each device that requires decryption for access.
systemd-cryptsetup [at] .service will ask for hard disk passwords via the m[blue]password agent logicm, in order to query the user for the password using the right mechanism at boot and during runtime.
At early boot and when the system manager configuration is reloaded, /etc/crypttab is translated into systemd-cryptsetup [at] .service units by systemd-cryptsetup-generator(8).
