Hi!

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... Pavel -- 64 bytes from 195.113.31.123: icmp_seq=28 ttl=51 time=448769.1 ms
