Shit, just linux.

Use this community for anything related to linux for now, if it gets too huge maybe there will be some sort of meme/gaming/shitpost spinoff. Currently though… go nuts

TIL the French government may have broken encryption on a LUKS-encrypted laptop with a "greater than 20 character" password in April 2023.

When upgrading TAILS today, I saw their announcement changing LUKS from PBKDF2 to Argon2id.

The release announcement above has some interesting back-of-the-envelope calculations for the wall-time required to crack a master key from a LUKS keyslot with PBKDF2 vs Argon2id.

And they also link to Matthew Garrett's article, which describes how to manually upgrade your (non-TAILS) LUKS header to Argon2id.
