Groups - OFFICE-2656 Demonstration of documentsignature.xml (OFFICE-2656-documentsignature.zip) uploaded

  • 1.  Groups - OFFICE-2656 Demonstration of documentsignature.xml (OFFICE-2656-documentsignature.zip) uploaded

    The document named OFFICE-2656 Demonstration of documentsignature.xml
    (OFFICE-2656-documentsignature.zip) has been submitted by Dennis Hamilton
    to the OASIS Open Document Format for Office Applications (OpenDocument) TC
    document repository.
    
    Document Description:
    This Zip package contains an extract of a META-INF/documentsignature.xml
    file.  
    
    1. In the only known-to-me established implementation of ODF 1.2 package
    signatures, a bug in how URIs of the form "#fragment" should
    fail, since the correct URI is
    "#META-INF/documentsignature.xml#fragment"
    
    2. Demonstration that the references to resources that are part of the
    signed material are always references to the extracted file streams and not
    the compressed (or encrypted) Zip content.  In particular, the references
    to fragments could not possibly be usable in that case, including
    cross-references in package file META-INF/documentsignature.xml itself.

    Why do you think that would be the correct URI? We don't have any 
    specific rules about fragment URIs. A "#fragment" references the id 
    "fragment". I fail to see why the URI should look like the one you 
    suggest. Where in the specification did you find rules that say so?

    Can you please explain what you mean by that? What in file demonstrates 
    that references always unencrypted uncompressed data?
    
    Thank you
