Darren Moffat about ZFS encryption
Darren wrote three really interesting articles about ZFS encryption: The first one is Introducing ZFS Crypto in Oracle Solaris 11 Express. This blog entry gives you a first overview how to use encryption for ZFS datasets. The second one titled “Assured delete with ZFS dataset encryption” explains how you can use the encryption feature to implement assured deletion with the “throwing the keys away” technique. Last but not least the article “Having my secured cake and Cloning it too (aka Encryption + Dedup with ZFS)” explains how deduplication and encryption work together in Solaris 11 Express.
