srm is a project that attempts to provide secure file deletion options to the familiar rm command used in all Unix derivatives. srm is fully compatible with the regular rm command, therefore there's no learning curve involved. There are 3 options for secure deletion.
- -s, --simple : Simple one pass overwriting with random data. (Least secure option.)
- -P, --openbsd : Emulates OpenBSD behaviour by overwriting in 3 passes.
- -D, --dod : Conforms to the US DoD specification of overwriting in 7 passes.
Although it is dificult to guarantee total security, srm is a good open source solution for normal users who wish to keep their data private. A determined government agency might still get to your data, but certainly not your pesky script-kiddie cousin.
