NEB-WIPE(1)

NAME
neb-wipe - Erase harddisk partitions in a very secure manner

SYNOPSIS
neb-wipe [ -r count ] partition

DESCRIPTION

neb-wipe uses the 35-pass overwrite method suggested by Peter Gutmann in https://www.usenix.org/publications/library/proceedings/sec96/full_papers/gutmann/

OPTIONS

-r <count>
    Do not use the Gutmann method. Instead, overwrite the partition with count passes of random data.

-h  Show the usage.

EXAMPLES
neb-wipe -r7 sd0a

TODO
35 pass is not required for all encoding schemes. Maybe add a switch to select overwrite patterns matching a desired scheme.

The used random numbers are generated by random(3), initialized with an unsigned 32 bit seed read from /dev/urandom. Reading all numbers from urandom is better since it contains entropy, but unfortunately this is way too slow. Maybe add a compiled-in faster entropy random generator.
