NAME
systemd-cryptsetup@.service, systemd-cryptsetup - Full disk decryption logic
SYNOPSIS
systemd-cryptsetup@.service /usr/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 this /etc/crypttab is translated into systemd-cryptsetup@.service units by systemd-cryptsetup-generator(8).
