<> <> Here is a list of tools for secure deletion of data stored on hard discs. Note that the security of these tools has not been well-established. They might prove vulnerable to a much greater extent than advertised by the authors. Do also note that the need to use such tools at all on modern disks is [[http://www.nber.org/sys-admin/overwritten-data-gutmann.html|disputed]]. Also, remember that copies of the data may be stored in temporary/cache files, file system slack (old data in partly used blocks), bad blocks, file system journals and other places. == Tools in Ubuntu == === main === ||'''Package'''||'''Command name'''||'''Upstream author'''||'''Downloaded from'''|| ||[[http://packages.ubuntu.com/coreutils|coreutils]]||shred||Colin Plumb; The GNU Project||probably http://www.gnu.org/software/coreutils/|| === universe === ||'''Package'''||'''Command name'''||'''Upstream author'''||'''Downloaded from'''|| ||[[http://packages.ubuntu.com/wipe|wipe]]||wipe||Berke Durak ||http://lambda-diode.com/software/wipe|| ||[[http://packages.ubuntu.com/secure-delete|secure-delete]]||srm, sswap, smem||van Hauser ||http://www.thc.org|| == Guides == http://www.techthrob.com/tech/securedelete.php == Tools not in Ubuntu == ||'''Package'''||'''Command name'''||'''Upstream author'''||'''URI'''|| ||srm||srm||Matthew D.
