One possible SSL library is OpenSSL from libbsd. Most likely that's the
simplest choice. For some other project we have also build libressl
without bigger problems before OpenSSL was included in libbsd. But that
was without RSB.

Another interesting SSL library would be mbed TLS. It promises to be a
lot smaller than OpenSSL. But I didn't try that one yet.
