In ODF files saved with password encryption, unzip it & look into
/META-INF/manifest.xml for info on type & parameters of the
encryption used.


Looking for current documentation.


The Open Document Format has this encryption feature standardized, the
details are available here:

* https://opendocumentformat.org/guidance/security/
* actual standard text:
  
https://docs.oasis-open.org/office/OpenDocument/v1.3/cs01/part2-packages/OpenDocument-v1.3-cs01-part2-packages.html#__RefHeading__752811_826425813


Since this is the dev list - the code performing the actual stream
encryption is here:

Hi, where do I find information regarding the encryption used with the 
"Save with password" option?


I have looked everywhere and cannot find this.  I looked for some 
community support but it seemed like some of the info was 
guessing/assuming what is done.  I found release notes about AES256 
being used but that was for v3.5 a long time ago.  No info in the guides 
either.


Looking for current documentation.

Thanks for any help with this!
