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 this /etc/crypttab is
       translated into systemd-cryptsetup@.service units by systemd-cryptsetup-generator(8).
