Hi.
I did a small modification , make cryptsetup funny , these code is not
secure as i didn't verify changes on ogg123 & sound files.
When typing in wrong codes , you'll hear a woman voice `access denied' ,
and '`access granted' for right password.
I can't spread the sound file anyway , it's from DOOM 3 for linux.

Just for fun as i said , if anyone like it ;-)
What do you guys think , i'd like to grab your opinions ;-)
P.S: if your system got attacked by a hacked /usr/bin/ogg123 or sound
files, that's ..
