The built-in default for cryptsetup on Fedora is LUKS2 which uses argon2id with parameters: Iteration time: 2000, Memory required: 1048576kB, Parallel threads: 4 It is possible to specify a different memory requirement at luksFormat time. But I'm not sure if there's any warning emitted by cryptsetup if there's significant memory pressure, i.e. high potential that a future Fedora might fail to open this volume. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
