[OASIS Issue Tracker] Created: (OFFICE-3853) Add Threefish encryption

Add Threefish encryption
------------------------

                 Key: OFFICE-3853
                 URL: http://tools.oasis-open.org/issues/browse/OFFICE-3853
             Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
          Issue Type: Improvement
          Components: Part 3 (Packages), Security
    Affects Versions: ODF 1.2, ODF 1.1
            Reporter: Robert Weir 
            Assignee: Robert Weir 
             Fix For: ODF 1.3


ODF 1.2 Part 3 section 4.8.1 "manifest:algorithm-name" lists identifiers for the various supported encryption algorithms.

We should add an identifier for the Threefish cipher.   This algorithm, from the same author as Blowfish, also comes with a copyright-free implementation and the author has declared that he has not patented it:

Scheier also recommends Threefish over the Blowfish.

For backwards compatibility we probably will still want to default to Blowfish in cases where the algorithm-name attribute is missing.
