Mark Minasi is
presenting a some features of the new Microsoft OS Windows Vista. He talks about not to use pagefile encryption :
You can encrypt your pagefile
Here's good news for the completely paranoid: You can encrypt your pagefile. Just take my adviceā¦don't. Not unless you want to wait, say, an hour or so every time you turn your computer on while you wait for it to decrypt a gigabyte or so of pagefile.
Since I am so used to encrypt the swap file in OpenBSD, I am asking myself two things. First of all, shouldn't the swap be encrypted anyway ? And the more important thing, what the hell should windows want from the pagefile during the boot process? I can't think of anything useful in the swap at boot time.
So either Microsoft engineers smoked some really heavy stuff, while they were implementing new cool security features or Mark Minasi is simply assuming the worst of them. If you know, which way it is, please let me know.
