You mentioned Botan. I already have a C++ => D Wrapper project going over  
here: https://github.com/ellipticbit/titanium

I am working out a bug where the memory corrupts itself when passing data  
back to D but it works and most of the leg-work is done. And I am  
definitely open to pull-requests.
