| </span><span class="doccomment">//! Async TLS streams |
| //! |
| //! This library is an implementation of TLS streams using the most appropriate |
| //! system library by default for negotiating the connection. That is, on |
| //! Windows this library uses SChannel, on OSX it uses SecureTransport, and on |
| //! other platforms it uses OpenSSL. |
| //! |
| //! Each TLS stream implements the `Read` and `Write` traits to interact and |
| //! interoperate with the rest of the futures I/O ecosystem. Client connections |
| //! initiated from this crate verify hostnames automatically and by default. |
| //! |
| //! This crate primarily exports this ability through two newtypes, |
| //! `TlsConnector` and `TlsAcceptor`. These newtypes augment the |
| //! functionality provided by the `native-tls` crate, on which this crate is |
| //! built. Configuration of TLS parameters is still primarily done through the |
| //! `native-tls` crate. |
