.SH "DESCRIPTION"
.PP
systemd\-cryptsetup@\&.service
is a service responsible for setting up encrypted block devices\&. It is instantiated for each device that requires decryption for access\&.
.PP
systemd\-cryptsetup@\&.service
will ask for hard disk passwords via the
\m[blue]\fBpassword agent logic\fR\m[]\&\s-2\u[1]\d\s+2, in order to query the user for the password using the right mechanism at boot and during runtime\&.
.PP
At early boot and when the system manager configuration is reloaded,
/etc/crypttab
is translated into
systemd\-cryptsetup@\&.service
units by
\fBsystemd-cryptsetup-generator\fR(8)\&.
