I use a series of older versions as part of my document forensics work. In particular, I keep ODF 1.1 processors around.
It happened that it is the default application in the same VM where I have OOo-dev 3.4 installed. So it opened by accident on a double-click where I was testing for the Save As with Password problem, to see if it existed in OOo-dev 3.4. So I found a down-level regression by happy accident. And that had me learn that the OOo-dev 3.4 uses AES encryption by default, which no ODF 1.0/1.1 client will recognize, nor will many ODF 1.2 apps not built to recognize anything more than the default encryption (there being no requirement that they do otherwise). To confirm how much down-version breakage there might be I tried these: LibreOffice 3.4.2 fails on the document in exactly the same way that OO.o 2.4.1 does. So does Lotus Symphony 3.0.0 FP3. So maybe the first Apache OO.o release should not switch from the default encryption algorithm so hastily. - Dennis -----Original Message----- From: Rob Weir [mailto:[email protected]] Sent: Friday, September 16, 2011 10:30 To: [email protected] Subject: Re: AOOo can't save passwort protected file On Fri, Sep 16, 2011 at 1:24 PM, Dennis E.
