Hi,
I implemented basic WS-Security-compliant digital signature support for SUDS
as a message plugins, so it's usable without modifying the library source
code. I put most information necessary to try it into the README.md file, in
case you're interested about the internals, I've written my masters thesis
about it, latter can be downloaded from
http://vsza.hu/thesis-beta.pdf
I tested my solution with Apache CXF, so any other interoperation experiences
are welcome, along with other suggestions and/or patches.
The code can be downloaded from my GitHub repository:
