Which version of OpenSSL?

This CSP cannot do SHA2 hashes so won't work unless you restrict
signature algorithms or set TLS version to 1.1. I believe OpenSSL
1.1.0 will try to load The ".. Enhanced RSA AES .. Provider" which
can handle SHA2 and may work. I say "may" because, if the key store is
a legacy hardware token, it also depends on signature algorithms supported
by the token and may be necessary to downgrade to TLS 1.1.
