I personally doubt there is any cipher+scheme that is 'save', if you can get a hand on 16 TB of encrypted data (an thus have enough data for analysis). Are you using a hardware raid for those 16TB? Concerning supported ciphers and modes of operation cat /proc/crypto should give you a vague idea. the usual syntax, btw. ist: algorithm-block mode-initialization vector afaik, so benbi would be a scheme/algorithm for initialization vectors as ESSIV (i.e.) Regards -Sven On Mon, March 9, 2009 17:29, Hari Sekhon wrote: > Stefan X wrote: >> Hi! >> For years I was thinking the ESSIV cipher mode is supposed to be the >> preferred mode.
