Cryptsetup/LUKS does not itself enforce any passphrase quality, it is libpwquality that libcryptsetup can be linked to (optionally, we use it in all Red Hat distros). See man for pwquality library (the idea is to enforce password policy for the whole distro, so it uses configuration pwquality file). > I checked for the --test-passphrase, but that verifies if the > passphrase would decrypt an existing device, which is not what I want. This tests only LUKS, pwquality is called only in Format. m. _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
