Windows and Mac OS were not designed as secure operating systems.
Your keystrokes, which might contain a sensitive passphrase, are
saved to disk, and your word processor routinely writes scraps of
your documents to disk.
These file scraps and keyboard strokes are automatically "deleted"
by your operating system or application and therefore seem to be
completely gone. However, they are only marked as free space by
the operating system; the actual contents of the files are still
visible to anyone with a low-level disk utility and the desire to
view your sensitive data.
Use Kremlin Wipe to wipe free memory, unused disk space or completely
wipe the disk!
When you choose the Standard wipe option, Kremlin Wipe wipes all
free space on the selected volume(s). It creates a file in the root
directory and writes data to it until it fills all available space.
The Wipe Memory option wipes all free memory.
This includes physical memory and virtual memory (the swap file).
You should close all open applications before using the Wipe Memory
The Thorough wipe option, like the standard
option, wipes all free space on the selected volume(s). It also
wipes the file slack of every file on the selected hard volume.
The file slack is the space between the end of the file and the
end of the hard volume cluster. The file slack often contains snippets
of sensitive data. Hidden and system files cannot have their slack
wiped and will be skipped.
The Complete wipe option completely wipes the selected volume(s).
This will render any data on the hard volume unrecoverable, and
should be used with great care.
