I'm assuming that when you boot, you do get /one/ prompt for your
passphrase, and not zero. If it doesn't ask /again/ after that,
then I'd guess that it's storing something somewhere.

In the little I've read about this, I've come across a scheme where
Grub writes an initrd file in memory and appends it to your main
initrd(s) so that the kernel can read it later.

I don't use hibernation. I close down desktops because I can remotely
boot them, and I leave laptops running as they consume trivial power.

You probably need to follow appropriate lists if you want to stay
up to date.
