The new SSL implementation is based on the new ssl.MemoryBIO which is only available on Python 3.5. On Python 3.4 and older, the legacy SSL implementation (using SSL_write, SSL_read, etc.) is used. The proactor event loop only supports the new implementation. The new asyncio.sslproto module adds _SSLPipe, SSLProtocol and _SSLProtocolTransport classes. _SSLPipe allows to "wrap" or "unwrap" a socket (switch between cleartext and SSL/TLS). Patch written by Antoine Pitrou. sslproto.py is based on gruvi/ssl.py of the gruvi project written by Geert Jansen. This change adds SSL support to ProactorEventLoop on Python 3.5 and newer! It becomes also possible to implement STARTTTLS: switch a cleartext socket to SSL.
