There were initial patches from Anand Jain back in September, but they weren't well-received in terms of the (lack of) cryptography design. IIRC, the patches provided file-level data encryption without encrypting metadata. I haven't seen anything since then (although Anand was planning on doing a session on btrfs encryption at LSF/MM in March -- I don't know if that happened, or what the outcome was). So, there's some interest in a fairly minimal implementation, but progress doesn't seem to be particularly fast. Hugo. -- Hugo Mills | "Are you the man who rules the Universe?"
