Documentation for PGP Shredder says it "overwrites your data with random text. It repeats this multiple times or passes.
The PGP Shredder alows setting for 3 passes up to over 40 passes.
Can someone tell me what the random characters are: maybe (in the 3pass scenario) a character, its complement, then with a random character?
What about in the 11 pass scenario?
thank you
