  • Lost your luks passphrase? You can always bruteforce from the command line. See the sample output, a simple command for the "pass" word, using combinations of upper/lowercase or number replacement. The generated combinations are: for a in {p,P}{a,A,4}{s,S,5}{s,S,5}; do echo $a; done pass pasS pas5 paSs paSS paS5 ... Show Sample Output

    for a in {p,P}{a,A,4}{s,S,5}{s,S,5}; do echo $a|cryptsetup luksOpen /dev/sda5 $a && echo KEY FOUND: $a; done

  • This is a safest variation for "sitepass function" that includes a SALT over a long loop for sha512sum hash Show Sample Output

  • Overwrite all sectors with zeros in one pass with ETA and speed status. If you wish to do more passes, encapsulate the line in a for loop (7 pass example): for f in `seq 1 7`; do pv -s `fdisk -l /dev/sdX|grep "Disk /"|cut -d' ' -f5` /dev/zero >/dev/sdX ; done Note: Substitute /dev/sdX with the correct drive you wish to erase. Also, you may have to be root to execute the command. Show Sample Output

    pv -s `fdisk -l /dev/sdX|grep "Disk /"|cut -d' ' -f5` /dev/zero >/dev/sdX
