NAME
systemd-cryptsetup@.service, systemd-cryptsetup - Full disk decryption
logic
SYNOPSIS
systemd-cryptsetup@.service
/lib/systemd/systemd-cryptsetup
DESCRIPTION
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[1], 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).
