Re: Digital Signature support for ODT files?

Hi,

I'm interested in adding digital signature to odf4j too. I
have some
experience with XML Signature, but I'm newbee to odf4j
development.
So, tell me if i can help ...

Just a comment. JDK 6.0 is not mandatory, you can JSR 105
implementation from Apache XML Security:

http:/
/xml.apache.org/security/Java/index.html

Thanks ;)

To get started, check out the odf4j code from the CVS
(http://odftoolkit.openoffice.org/source/browse/od
ftoolkit/odf4j)

Go ahead. Write some code and let us know.

looking forward to see your contribution.

Amit

Hi,

>From this link -
http://java.sun.com/developer/technicalA
rticles/xml/dig_signature_api/in
dex.html, I could know that for a single XML the application
of XML
Signature. But as ODF documents are number of compressed
XML's, how
should the XML Signature be applied to all those files?

Thanks and Regards,
Godha

Hi,

When you work with odf4j, you are working over a compressed
XML
(content.xml). For XML Signature, this is the same. You have
to
construct an XML Signature with several
"References" to the main XML
files (content, style, etc) ... if i'm not wrong

The example that you send, implements an enveloped
signature. That
means that no reference is necessary to external files,
because the
signature is enveloped by the data that must be signed. In
OpenOffice
we need to generate a dettached signature:

http://www.w3.org/TR/xmldsig-core/#def-SignatureDetached


But is quite similar ...
