SHA512 is not in the Cryptography package, but it would be great to see it there, with an appropriate plugin, of course, for performance. I am toying with the idea of extending SSL to include TLS 1.3, and that would require SHA512, plus it would be great to keep the Cryptography package current. Adding TLS 1.3 would be a fair amount of work requiring Diffie-Hellman group extensions to ephemeral elliptic curves, in addition. I am unsure what symmetric ciphers are used by TLS 1.3 also. The advantage is that it is automatically cross-platform, even with plugin generation, such that Cryptography could be used on the big 3 as well as on ARM, Android and iOS. I'll keep dreaming about it.
