dmarc=pass (policy=none) header.from=gnu.org X-TUID: 8BJ6i6eEOvEs Hi, Given the broad popularity of LUKS full-disk encryption among our fellow Guix users, I thought the community might appreciate reading about potentially weak key-derivation functions in older LUKS installations. [1] The article even offers fixes, although I cannot say whether your system will boot after you follow the steps since I do not use LUKS personally. Stay safe!
