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.[2][5][6][7][8][9]

nwipe was first released as version 0.17 on 20 October 2014.[10]

  • RCMP TSSIT OPS-II - Royal Canadian Mounted Police Technical Security Standard, OPS-II[5]
  • DoD 5220.22M - The United States Department of Defense 5220.22-M full 7 pass wipe.[5]
