-Creates a new secure pair object with two streams, one of which reads and writes
-the encrypted data and the other of which reads and writes the cleartext data.
-Generally, the encrypted stream is piped to/from an incoming encrypted data
-stream and the cleartext one is used as a replacement for the initial encrypted
-stream.
-
-`tls.createSecurePair()` returns a `tls.SecurePair` object with `cleartext` and
-`encrypted` stream properties.
-
-Using `cleartext` has the same API as [`tls.TLSSocket`][].
-
-The `tls.createSecurePair()` method is now deprecated in favor of
-`tls.TLSSocket()`. For example, the code:
-
-```js
-pair = tls.createSecurePair(/* ... */);
-pair.encrypted.pipe(socket);
-socket.pipe(pair.encrypted);
-```
-
-can be replaced by:
-
-```js
-secureSocket = tls.TLSSocket(socket, options);
-```
-
-where `secureSocket` has the same API as `pair.cleartext`.
