When the password is left empty the swap is encrypted with a random password
which is lost at shut down. So every boot you have a fresh swap. So PLEASE
don't disable swap encryption when the password is left empty since I then
don't have an encrypted swap or I have to type another password at boot! This
is in my opinion the way it is meant to be.
Concerning hybernate and encrypted swap, if you seach the internet you will
find it is impossible to hybernate to an encrypted swap. I made a workaround by
creating an extra swap partition that is not used by the system. I add this
swap to grub and added a script in /etc/pm/sleep.d which will swapon this swap
as the first thing when hibernate is started, and swapoff when the system is
resumed. I have tested it and this works great. Of course you would want to
change resume so it encrypts the hybernate image to the swap, it doesn't make
sense to encrypt your swap and then use an unencrypted hybernate image with all
your running stuff open for any visitor.
