*Description*
-------------
The ODF1.2 specification allows to use W3C-specified algorithms to
encrypt ODF1.2 documents. The new implementation let the following
algorithms be used in case ODF1.2 encrypted document is stored:
Start key generation: SHA256
Derived key generation: PBKDF2
Encryption algorithm: AES-256
Checksum generation: SAH256_1K

It is possible to let start key and checksum generation use
SHA1/SHA1_1K algorithms during storing of ODF1.2 encrypted document by
setting the configuration entry
org.openoffice.Office.Common/Save/ODF/UseSHA1InODF12
to "true". It is also possible to let Blowfish algorithm be used in
this case by setting the entry
org.openoffice.Office.Common/Save/ODF/UseBlowfishInODF12
to "true".

The storing of encrypted ODF1.1/ODF1.0 documents is not affected.

Please see

for details.
