From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Do I really have to use secure erase (sopuli.xyz)

I am giving away a shitty 128GB SSD, which was used with LUKS 2 for most of it's lifetime. As far as I know, it's good practice to secure-erase it, but I'm too lazy to reinstall the OS on it (I already did it once). Is it really needed?

You said that:

This leads me to assume that it is not now? Is this the case? If it still has LUK2 on it, you can run cryptsetup-erase on the luks2 container. This won't wipe any unencrypted data, though.

One needs to be careful and avoid block level wipes wherever possible for SSD as this will wear it out quicker. Obviously, if you have sensitive data unencrypted, you may have to. Shred is your friend, here. It works on entire devices as well as individual files. The individual files option is preferable if you the sensitive data is at known locations.

Does shred work on journaling file systems?
