Thank you Adam for your work in the D community.  Thanks for the 
heads up.  Yes, definitely OpenSSL (or any security library) 
isn't had for free in a secure Internet and I will need to make 
some effort to ensure I get that working.  In my limited use case 
(does not need to run ANYWHERE, but in a specific environment) it 
should be possible.  Will update as soon as I know.
