The operating system overwrites disks and memory with random bits both just after it is released and just before it is allocated again. It also allocates new memory and disk space randomly, rather than just handing you the next 20 blocks/sectors. It is a /very/ paranoid operating system. And the numerous precautions it takes make it very slow and a little annoying to use. > Encrypting the overwrite character(s) would give the encryption attacker a > cleartext -- a bad move right out of the "Imitation Game". This is the sort of reason I'm reluctant to freak the underlying platform. The people who designed/wrote it are good at their jobs and I have to worry about only programmer-level things. If the platform itself (OS/hardware) leaks information that's not my concern. Simon.
