Yes, that is what would happen if computers didn't come with a integrated cryptoprocessor to store secrets or something like TPM2, but computers do come with that now. You could require a secret stored in it as apart of the process of unlocking the drive, either deriving a key from both parameters (the key-derived password and the secret in TPM) or having the TPM secret decrypt the configuration that stores the password hash and parameters Since you can't easily mirror data from a TPM chip, especially if it's integrated deep into the CPU, wiping it would render the contents on the drive useless even if they mirrored it beforehand On Thu, Nov 06, 2025 at 10:34:26AM -0500, Chris X Edwards wrote: > I don't really have any true expertise to comment publicly but how > about this: > > You have an encrypted drive with important stuff on it.
