nwipe is a Linux computer program used to securely erase data. It is maintained by Martijn van Brummelen and is free software, released under the GNU General Public License 2.0 licence. The program is a fork of the dwipe program that was previously incorporated in the DBAN secure erase disk.[2][3][4][5][6]
nwipe was created to allow dwipe to be run outside DBAN, using any host distribution. It utilizes a simple text-based ncurses user interface or can be run directly from the command line. It is available as an installable package in the repositories of many Linux distributions, including Debian and Ubuntu.[3][6][7][8][9][10]
nwipe was first released as version 0.17 on 20 October 2014.[11]
