systemd-cryptsetup@.service, systemd-cryptsetup — Full disk decryption logic
systemd-cryptsetup@.service
/usr/lib/systemd/systemd-cryptsetup
systemd-cryptsetup@.service
is a
service responsible for setting up encrypted block devices. It is
instantiated for each device that requires decryption for
access.
systemd-cryptsetup@.service
will ask
for hard disk passwords via the
password agent logic, 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@.service
units by
systemd-cryptsetup-generator(8).
