🌸 NAME 🌸

sswap — secure swap wiper, like the whole secure_deletion toolkit vibe 💖

🦋 SYNOPSIS 🦋

sswap [-f] [-l] [-l] [-v] [-z] swapdevice

✨ DESCRIPTION ✨

okay so bestie, sswap is literally designed to delete data that might still be lurking on your swapspace, and it does it in a way that cannot be recovered — not by thieves, not by law enforcement, not by any other threat. no cap. 🫶

the wipe algorithm is based on the paper "Secure Deletion of Data from Magnetic and Solid-State Memory" presented at the 6th Usenix Security Symposium by Peter Gutmann, one of the leading civilian cryptographers. king behavior honestly 👑

the secure data deletion process of sswap goes like this:

  • 1 pass with 0xff
  • 5 random passes. /dev/urandom is used for a secure RNG if available.
  • 27 passes with special values defined by Peter Gutmann.
  • 5 random passes. /dev/urandom is used for a secure RNG if available.

like. twenty-seven passes. that's not a vibe check, that's a whole personality 💅

💅 COMMANDLINE OPTIONS 💅

  • -f — fast (and insecure mode): no /dev/urandom, no synchronize mode. insecure bestie, we do NOT gatekeep that warning
  • -l — lessens the security. Only two passes are written: one mode with 0xff and a final mode with random values.
  • -l — -l for a second time lessons the security even more: only one pass with random values is written.
  • -v — verbose mode ✨ (she tells you everything, main character energy)
  • -z — wipes the last write with zeros instead of random data
ngl the double -l is doing the most, but it's iconic and we respect it 🎀

🚨 BEWARE 🚨

swapoff — unmount your swapspace before using this tool! Otherwise your system might crash!

fr fr. unmount it FIRST. your system WILL crash otherwise and that is not the slay you want. 😭

BETA! sswap is still beta. It was only tested on Linux but on this system it performed it's work all of the time.

💀 BUGS 💀

No bugs. There was never a bug in the secure_deletion package (in contrast to my other tools, whew, good luck ;-) Send me any that you find. Patches are nice too :)

not the author roasting his own other tools 😭 we love a humble icon 🙈
