If you use systemd with plymouth you will get this automaticaly, as
plymouth will cache the password for you.

There has been a long-standing TODO list item to use the kernel keyring
as cache for HDD passwords, and then optionally even open this up to be
useful for no-password logins for default users, which can be used to
unlock the gnome keyring or suchlike.
