| 647 | The message callback provides a debugging hook to analyze TLS |
| 648 | connections. The callback is called for any TLS protocol message |

| 650 | Due to technical limitations, the callback can't be used to filter |
| 651 | traffic or to abort a connection. Any exception raised in the |
| 652 | callback is delayed until the handshake, read, or write operation |
| 653 | has been performed. |
