Hello,
We want to include some graphical information alongside with
signature/certificate -
a photo/logo or graphical signature.
(Others are responsible for standardt ways to include this in/wiht certificate,
and I try to find out, how to present it in OOo)
I think of extention to show the images in dialog box (small window
similar to document-navigator)
this would also include standart signee info: name/surname at least.
how hard (much time) would it be to achieve? what might be most difficult?
Speaking of openxades, make sure what the requirements for the
signatures are. OOo's XML Digital Signature may not be suitable for your
clients, for example, it may not be legally accepted.
what api parts shoud I study before?
There is a bunch of unpublished api at
http://api.openoffice.org/docs/common/ref/com/sun/star/security/module-ix.html
http://api.openoffice.org/docs/common/ref/com/sun/star/xml/crypto/module-ix.html
Because it is unpublished you cannot rely on these interfaces remain stable.
The API (Interfaces) are not yet capable of passing additional
information such as images.
You would have to implement your own dialog. But then you need to put in
a lot of "signature code". You cannot reuse all available code, since
the gui code is mixed with signature code (look at
xmlsecurity/source/dialogs/digitalsignaturesdialog.cxx)
It is difficult to guess the effort, but be sure that this is a huge task.
could you propose similar extention examples?
is ooo digital sigs api somehow connected with http://openxades.org ?
no

Thanks in advance
