(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.

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".

I think I have mentioned before that it is easy to provide an extension 
to switch the relevant configuration settings.

As the release manger I will accept the issue as critical enough to 
change the default back for 3.4. For AOO 4.0 we will switch the default 
again and will provide a GUI to allow the user the change it more easily.

For 3.4 we provide a mini extension that switch the default back to AES 
for users who prefer this encryption algorithm.
