The filesystem also should be able to store data in non-encrypted form. A search on web shows a few encrypted filesystems like "Crypto" from Suse Linux, but we need a system where encryption will be a choice per file. We have a hardware controller to apply encryption algorithm. If a filesystem provides hooks to use a hardware controller to do the encryption work then the cpu can be freed from doing the extra work. Any comment on this? Kallol NucleoDyne Systems. nucleon@nucleodyne.com 408-718-8164
