 A partial wrapper for [xmlsec](https://www.aleksey.com/xmlsec).
 
 As seems to be the case for many things in the XMLish world, the xmldsig and xmlenc standards are more complex that may be nessesary. This library is as general as I could reasonably make it with an eye towards supporting the parts of the standards that are needed to support a SAML implementation. If there are missing bits you feel you need, please raise an issue or submit a pull request.

 It may annoy you to grow a depenency on the shared libraries for libxmlsec, libxml2, etc. After some fighting, here is what I made work on Linux to get
 a static binary. See also `Dockerfile.build-static` which build the example
 program using this method.
