I'd like to use suds with ws-security.  There is a minimal wsse implementation, but without support for signing the message.

Here's the spec:
http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/#sec-o-Simple

I've looked around and found bits and pieces of implementation, notably this ZSI impl:

http://www.java2s.com/Open-Source/Python/Web-Services/ZSI/ZSI-2.0/ZSI/twisted/WSsecurity.py.htm

and this research:

http://proj.badc.rl.ac.uk/ndg/wiki/T12_Security/WS-Security

I wouldn't mind implementing this and contributing it back into Suds (which I love by-the-way).  But I don't want to re-invent the wheel.  

If anyone on this knows of any other existing python implementations of ws-security, please point me in the right direction.
