Re: Death of DRM on PC platforms??

Keep a password encrypted until use, and then overwrite the plain text after you're done with it. Sorted.

You need the keys in memory too though, so this is a form of security by obscurity. A relatively tough one, but someone motivated enough to get into an application's secured memory area is also going to be able to deal with that. Unless you're doing completely homomorphic computation (I'm not sure it's actually possible and still decodeable at a low cost) control of the hardware always offers the potential to compromise a system running on it. Encryption at rest is a different thing which you can achieve.
