Basic Usage
===========
The SSL/TLS protocol works securing an underlying TCP connection, this module
adds the secure layer around the Python standard library
`socket <https://docs.python.org/3.6/library/socket.html>`_ module.
There are three different paths to secure a socket in this module:
* Using the top level function wolfssl.wrap_socket();
* Using the method wrap_socket() from a SSLContext instance;
* Creating an SSLSocket object from the scratch.
Note 1:
It is possible to use the same SSLContext for multiple SSLSockets to save
time and resources.
Note 2:
Each path provides its own options for fine-tuning the securint parameters.
Check them out in the API documentation.
Using the top level function wolfssl.wrap_socket()
--------------------------------------------------
.. code-block:: python
>>> import socket
>>> import wolfssl
>>>
>>> sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)
>>>
>>> secure_socket = wolfssl.wrap_socket(sock)
>>>
>>> secure_socket.connect(("www.python.org", 443))
>>>
>>> secure_socket.write(b"GET / HTTP/1.1\n\n")
>>>
>>> print(secure_socket.read())
