Hi Charles,

I am a forensics teacher.

There is another point to be considered: the RAM memory. The data,
commonly, pass across RAM and is easy get the key from a memory dump
(even if the computer was turned off). So, after take care of the SDD,
you need to wipe the RAM. An 'apt-get install secure-delete' wil
provide sdmem command, that will wipe the RAM. I suggest to use a
live-CD or flash drive with Debian to boot in shell only mode and run
sdmem. You can install Debian in a flash drive and use it. It is easy
to do.

Regards,
