RE: [libreoffice-users] password problem

Bob, the META-INF/manifest.xml file should be a text file.  Why do you think it is a binary file?  
It should be in a META-INF folder where you extracted Experience.zip.

The manifest.rdf file is encrypted (so it looks like binary).  That is not the one that matters.  
In fact, one of the first things we need to do is remove it from the document and from the 
manifest.  There are other parts of the document that are unnecessary and that we can remove as 
well.  With any luck, it will be one of those that is corrupted.

NEXT STEPS:

Take a look at META-INF/manifest.xml.

We can attempt to repair the manifest.xml file without seeing the rest of Experience.odt.  We can 
send modifications back to you and you will need to try using them to replace the 
META-INF/manifest.xml, re-zip the document, and see if it then opens with your password.  It may 
take several tries, and we can still fail.

This should prevent any of the personal, confidential information from leaving your custody.  If 
you are able to open META-INF/manifest.xml, you should see that there is no personally-identifiable 
information in it.

Because manifest.xml might be damaged, you might need to put it in a Zip file all by itself before 
sending it to anyone.  That is more likely to pass through e-mail without further damage.  Then it 
can be examined, any corrections attempted, and returned to you with instructions about how to 
include it into an extraction and put the extraction back together as a document to try opening 
with your password.

OK, I did. No errors

OK understood

OK, I guess that means special knowledge by someone. I tried opening manifest 
ans see it is a binary. It needs something called knewstickerstub which I 
don;t have an aren't able to install. Might be able to find it somehow but 
don't really know if I need it.

Hmmm  How would I do that?

 - Dennis. I am sure you are a most trustworty person, but this document 
cntains very personal information which could even be dangerous to me. That 
is why it is encrypted. I was/am a fairly high ranking officer  in a federal 
law enforcement agency.  I would have to give that some very serious thought.
