The problem with overwriting keys in RAM while the computer's running is that it makes it a lot harder to do the encryption without the keys. If there are keys in RAM, it's because the program wants them to be in RAM so it can use them. > > 2. how long do the bad people have to read your memory after you turn it > > off? > > > How long do you need to search the memory?

The question is, after you push off, how long does it take someone to boot their OS and read your data and how does this compare with the lifetime of your data? Is it possible to make booting the computer slower than that? Like, if I use a BIOS password, can they still boot from a CD in 30 seconds, 5 minutes, whatever?
