Well, yeah-- I am but I can use the command line in a pinch, thanks.
I've been around since DOS but hoped those days were behind me. I
switched to Mac because things are suposed to be easy!

Following Michelle's suggestion, I see PGP now has a Mac version and the
free version does have the shredder feature I'm looking for. OTOH, if
it's on the encrypted disk, I guess I can just delete it...

In my days with the DoD, your 'rm -P' wouldn't stand muster. 'srm' might
suffice but then there are still those agencies that would not only erase
but then ship the drive out for "special" dismantling. ;)

Writing 1, 0 and 1 some will claim will still allow them to read the pre-
viously written data.

Don't confuse PGP with the official government secret redundant data
destruction protocol, Pigeon Delete:

Well, I take comfort in being exceedingly looking -- rather than staying
up to date on news and info ;-)
