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.

Format drive if wrong decryption key is prompted? (sopuli.xyz)

Is there a possibility to make Linux install automatically delete the data if wrong decryption key is set x amount of times?

Would be nice too, if it started automatically to overwrite the data too even full disk overwrite takes a lots of time.

I tried to google docs, but I don't know the right words.

However, if it's enough to erase the data if wrong key is entered AND the original operating system is running it should be possible. But I agree, that limitation doesn't really make sense in a security point of view.

Besides that, I believe that luks encryption with sufficiently complex password (and updates) is practically the same than empty drive for the attacker. More interesting setup would be to give out different data depending on which key is given, there was some windows-based software which could do that back in the day, I'm not sure if it's still around and don't remember the name for it right now.

It would at least add a layer of obfuscation if someone extorts a key from the owner.
