P. Gutmann’s
algorithm
35
Peter Gutmann’s algorithm is very
sophisticated. It’s based on his
theory of hard disk information
wiping (see
http://www.cs.auckland.ac.nz/
~pgut001/pubs/secure_del.html
).

B. Schneier’s
algorithm

Bruce Schneier offers seven pass
overwriting algorithm in his Applied
Cryptography book. 1
st
pass – 0xFF,
2
st
pass – 0x00, and then five times
with a cryptographically secure
pseudo-random sequence.
