60 <para><filename>systemd-cryptsetup@.service</filename> is a
61 service responsible for setting up encrypted block devices. It is
62 instantiated for each device that requires decryption for
63 access.</para>
64
65 <para><filename>systemd-cryptsetup@.service</filename> will ask
66 for hard disk passwords via the <ulink

68 password agent logic</ulink>, in order to query the user for the
69 password using the right mechanism at boot and during
