+Connection security
+-------------------
+
+The JDBC driver and connector automatically use Transport Layer Security (TLS) encryption and certificate validation. This requires a suitable TLS certificate configured on your Hana database host.
+
+To enable encryption in the connection string, use the ``encrypt`` property:
+
+.. code-block:: none

+``trustStoreType``                                 File format of the truststore file, for example ``JKS``.

+``trustStore``                                     The path to the truststore file.

+A connection string using a truststore would be similar to the following example:
