+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 a public key.
+
+.. note:: In production environments it is recommended to make use of a
certificate signed by a certificate authority.
+.. note:: This tutorial uses Windows to create a self-signed certificate. For
Linux environments, other methods such as OpenSSL can be used.
+
+**Step 1 - Generating the Self Signed Certificate**
+
+To generate a self-signed certificate, run command prompt as administrator and
run the following commands.
+.. testcode::
+ dotnet dev-certs https --trust
+ dotnet dev-certs https -ep "<CertificateName>.pfx" -p <CertificatePassword>
+
+You will receive a prompt asking you confirm that you would like to trust this
certificate, select yes.
+You now have a self-signed certificate that your local environment trusts.
+
+**Step 2 - Converting the .pfx file into public and private keys**
+
+Since `dotnet dev-certs` does not let you export Public and Private keys
directly we need to convert the .pfx file.
+There are several way to achieve this and this tutorial uses OpenSSL (using
Windows Subsystem for Linux)
+to perform the conversion as per this `IBM article`_.
+
+**Step 3 - Running a server with tls enabled**
+
+We're going to use the pyarrow server example available on the `GitHub repo`_.
To run the server with TLS enabled, the python script should be
+called with the path to the public and private keys.
+.. testcode::
+ python server.py --tls CERTFILE <PathToPublicCertificate> --tls KEYFILE
<PathToPrivateKey>
Review Comment:
Have put in a minimal server example. I removed all overrides except the
code required to receive information from the client. Let me know if that's fine
