WebThe latest cryptsetup release added an option to let cryptsetup automatically detect the optimal sector size based on the (physical) sector size of the backing device. By using this new option we can make sure that Anaconda uses the optimal sector size for newly created LUKS devices during installation. Weba keyfile, see #Keyfiles. Both key types have default maximum sizes: passphrases can be up to 512 characters and keyfiles up to 8192 KiB. An important distinction of LUKS to note …
