systemd-cryptsetup: Full disk decryption logic

NAME

systemd-cryptsetup [at] .service, systemd-cryptsetup - Full disk decryption logic

SYNOPSIS

systemd-cryptsetup [at] .service

/lib/systemd/systemd-cryptsetup

DESCRIPTION

systemd-cryptsetup [at] .service is a service responsible for setting up encrypted block devices. It is instantiated for each device that requires decryption for access.

systemd-cryptsetup [at] .service will ask for hard disk passwords via the m[blue]password agent logicm[][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 [at] .service units by systemd-cryptsetup-generator(8).
