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.
This is the correct answer. Your best bet is to simply make your encryption as strong as possible, because once an attacker gains access, they will be able to clone the encrypted data and access it in any way they choose. Any sort of interventions you put in place will only work on your machine.
