NAME
sswap - secure swap wiper (secure_deletion toolkit)
SYNOPSIS
sswap [-f] [-l] [-l] [-v] [-z] swapdevice
DESCRIPTION
sswap is designed to delete data which may lie still on your swapspace in a secure manner
which can not be recovered by thieves, law enforcement or other threats. The wipe
algorythm is based on the paper "Secure Deletion of Data from Magnetic and Solid-State
Memory" presented at the 6th Usenix Security Symposium by Peter Gutmann, one of the
leading civilian cryptographers.
The secure data deletion process of sswap goes like this:
* 1 pass with 0xff
* 5 random passes. /dev/urandom is used for a secure RNG if available.
* 27 passes with special values defined by Peter Gutmann.
* 5 random passes. /dev/urandom is used for a secure RNG if available.
COMMANDLINE OPTIONS
-f fast (and insecure mode): no /dev/urandom, no synchronize mode.
-l lessens the security. Only two passes are written: one mode with 0xff and a final
mode with random values.
-l -l for a second time lessons the security even more: only one pass with random
values is written.
-v verbose mode
-z wipes the last write with zeros instead of random data
BEWARE
swapoff
unmount your swapspace before using this tool! Otherwise your system might crash!
BETA! sswap is still beta. It was only tested on Linux but on this system it performed
it's work all of the time.
