BTW Fedora used plymouth (graphical and text boot frontend)
for password prompt, then it pushed password to cryptsetup directly.

Recent versions use systemd, password prompt depends
on configuration (I think it can be still still plymouth) but unlocking
of disk is done by systemd itself (resp. system-cryptsetup
generator parsing /etc/crypttab translating it to separate systemd units).

Unlocking uses libcryptsetup only.
IIRC in Fedora boot process there is no cryptsetup binary used at all.

I would suggest to ask on systemd or Fedora devel list if you want
to change prompt then.
