Hi!
quoted
That's fine for the never-enter-a-password case, but for the 
suspend-case, it's not so good since i want to close the lid and pack 
away the notebook. Two scenarios, two implementations.
Your "close-lid with suspend-to-disk" without ever asking password in
suspend is fundamentally unfixable, unless you use public key
encryption, but for it to be secure you've to store in your brain and
type >128 chars at every resume...
?? You can store private key on harddrive and encrypt it by
symmetric crypto. No need for that huge passphrases.
But it's not secure anyways without encryption since the memory freed by
mozilla where the credit card was, could be dumped into the swap space
if it was only partially reused as slab etc.. I mean, even normal
swapping is insecure on a laptop, but suspend make it worse.
I believe this should be fixed, first. Then we can work on suspend/resume...
