I have managed to convine my company to allow me to use Linux (Ubuntu) as an operating system on my works laptop as I showed them Truecrypt working on XP and Ubuntu. They have now asked me what file shredding utility I’m using and I’m stumped. I have searched and can’t find one. It would really need to be a standalone program or (my preference ) a right click ‘Jobby’.
My company are very strict on file security due to theft of information.
In particular see the Put Shred on Steroids section.
Effectively… shred = 25 passes, random data and zeros secure-delete (srm) = 38 passes, random data and zeros, and cryptographic techniques developed by Peter Gutmann (who describes himself as “a professional paranoid”). The Gutmann method is an algorithm for securely deleting files and hard drives
Or for truly stand alone “entire drive secure erase” options… there is always the DBAN (Darik’s Boot and Nuke) LiveCD/LiveUSB:
If you’ve already installed nautilus-scripts-manager and restarted nautilus (reboot), you can easily get to the ~/.gnome2/nautilus-scripts folder by right-clicking somewhere, then selecting Scripts>Open Scripts Folder
Now check your Right-Click>Scripts context menu has an entry for Secure Delete.
Something to bear in mind… due to the limited write cycle capacity of USB memory sticks and SSD’s, the protracted use of “Secure Delete” (on them) may shorten the drives life… remember every time you “Secure Delete” something, that’s the equivalent of 38 write cycles (to one particular part of the drive)… though wear levelling may mitigate this to a certain extent.
