Hi Clemens, thank you for your answer! > IIRC, benbi uses 64 bit tweaks for xts where plain uses 32 bit. So I suppose I can safely choose aes-xts-benbi... Do you know where these options are further explained? (Google didn't yield but /one/ result for xts-benbi, and in the Linux kernel documentation I couldn't find anything) Best wishes from Hamburg, Ulrich --------------------------------------------------------------------- dm-crypt mailing list - http://www.saout.de/misc/dm-crypt/ To unsubscribe, e-mail: dm-crypt-unsubscribe@xxxxxxxx For additional commands, e-mail: dm-crypt-help@xxxxxxxx
