Wipe
Wipe is a secure file wiping utility.
It is based on work by Peter Gutmann.
Recovery
of supposedly erased data from magnetic media is easier than what many
people would like to believe. A technique called Magnetic Force
Microscopy (MFM) allows any moderately funded opponent to recover the
last two or three layers of data written to disk; wipe repeadetly
overwrites special patterns to the files to be destroyed, using the
fsync() call and/or the O_SYNC bit to force disk access. In normal
mode, 34 patterns are used (of which 8 are random). These patterns were
recommended in an article from Peter Gutmann entitled "Secure Deletion
of Data from Magnetic and Solid-State Memory". A quick mode allows you
to use only 4 passes with random patterns, which is of course much less
secure.
