RAM key encryption

[Daver]

To prevent cold boot and DMA attacks, is it possible to encrypt the keys in RAM (but still allow Windows hibernate and fast startup to work)?

[DavidXanatos]

I don't think that would work, I mean the key can be obfuscated somewhat but that is no real security.
I know veracrypt does such a think but as said its no real 100% secure protection just makes h attack a bit harder.
