Subject RE: [RELEASE,CODE]: Bug 119090 - Default Encryption Fails for Down-Level Implementations
Date Mon, 26 Mar 2012 01:15:19 GMT

I was doing some nosing around and, based on some information on the Community Forums (thank
you Hagar), it looks like the settings are controlled in a file called registrymodifications.xcu,
at least on Windows.  The location will vary with different versions of windows.

On windows, you can find one under the installed-user profile, such as Documents & Settings\orcmid\Application
Data [a hidden file], OpenOffice/3/user/registrymodification.xcu for any install since the
AES256 has been instituted as default.  the *.xcu is actually an XML file and you can find
the settings by searching for "blowfish" and for "SHA1".

How this works for Mac, Solaris, OS/2, and the various Linus and BSD builds, I have no idea.

... options to consider:

3. User change to config file, to use the new option.

I have suggested a writeup on this, but such instructions are much 
better aimed at the (few?) users who want the "latest and greatest" 
security option, and will do a little work to get it. (Does anybody know 
what that file name is? Given that, I volunteer to update the Release 

4. Macro to toggle the settings.

This could be distributed in a BASIC library (new or existing); no 
extension necessary. User instructions to find and run the macro are 
simple. I may be able to write this; preliminary investigation is 
promising but not certain. I volunteer to try. There are several real 
experts on this list, whom I might ask for help.
