They are the same underlying device, but they are not the same.
/dev/mapper/cryptswap1 has a layer of encryption ontop of it. /dev/sda6
does not. If you really want cryptswap, you probably also want to
hibernate encrypted, too. Otherwise, your memory gets dumped unencrypted
on hybernate, which is even worse than your swap not being encrypted.
I don't think there would be a problem with hybernating on a crypted
swap, it is the initrd that sets up the encryption layer, is it not?
Sounds like you might need to do a non-random key though.
Don't believe everything you think.
