Looking at the brutal wontfixing of that bug, maybe reconsider if the
existing engine interface can do PSS by simply having the CAPI/CAPIng
engine export the generic PKEY type for PSS-capable RSA keys.  Also,
maybe use a compatible stronger CAPI "provider" (their engines) to do
stronger hashes etc.

Enjoy
