+Authentication with certificates
+=================================
+
+Following on from the previous scenario where traffic to the server is managed
via a username and password,
+HTTPS (more specifically TLS) communication allows an additional layer of
security by encrypting messages
+between the client and server. This is achieved using certificates. During
development, the easiest
+approach is developing with self-signed certificates. At startup, the server
loads the public and private
+key and the client client authenticates itself to the server with the tls root
certificate.
+
+.. note:: In production environments it is recommended to make use of a
certificate signed by a certificate authority.
+
+**Step 1 - Generating the Self Signed Certificate**
+
+Generate a self-signed certificate by using dotnet on `Windows`_, or
`openssl`_ on Linux or MacOS.
+Alternatively, the self-signed certificate from the `Arrow testing data
repository`_ can be used.
+Depending on the file generated, you may need to convert it to a .crt and .key
file as required for the Arrow server.
+One method to achieve this is openssl, please visit this `IBM article`_ for
more info.
+
+
+**Step 2 - Running a server with TLS enabled**
+
+The code below is a minimal working example of an Arrow server used to receive
data with TLS. For a full server example, please visit the Arrow `GitHub
repo`_.
+
+.. testcode::
+
+ import argparse
+ import pyarrow
+ import pyarrow.flight
+
+
+ class FlightServer(pyarrow.flight.FlightServerBase):
+ def __init__(self, host="localhost", location=None,
+ tls_certificates=None, verify_client=False,
+ root_certificates=None, auth_handler=None):
+ super(FlightServer, self).__init__(
+ location, auth_handler, tls_certificates, verify_client,
+ root_certificates)
+ self.flights = {}
+ self.host = host
+ self.tls_certificates = tls_certificates
