+## Encryption Requirements
+
+{{% alert title="Note" %}}This step is only required if the load balancer installed is the load balancer that is included with the {{% ctx %}} software.{{% /alert %}}
+
+### Retrieve Existing Encryption Key
+
+On one of the Application Servers:
+
+1. On the Start menu, choose `Run`.
+1. In the open box, enter `regedit.exe`. You must have administrative credentials to run regedit.exe.
+1. In the Registry Editor, locate the registry value `Key` which can be found at the following location `HKEY_LOCAL_MACHINE\SOFTWARE\Innovise\Cerberus`.
+1. Copy the value of `Key` and save it to a known location.
+
+### Add Encryption Key to Load Balancer Server
+
+On the Load Balancer Server:
+
+1. On the Start menu, choose `Run`.
+1. In the open box, enter `regedit.exe`. You must have administrative credentials to run regedit.exe.
+1. In the Registry Editor, navigate through the subkeys to `HKEY_LOCAL_MACHINE\SOFTWARE\Innovise\Cerberus`.
+
+   If any of the subkeys do not exist create them, repeating for each subsequent subkey:
+
+    1. Right click on the parent subkey.
+    1. Select `New`.
+    1. Select `Key`.
+    1. Set the name to be the subkey that you are creating e.g. `Innovise`.
+
+1. Under the `Cerberus` subkey locate the registry value `Key`.
+
+   If the registry value does not exist create it:
+
+    * Right click in the right window.
+    * Select `New`.
+    * Select `String`.
+    * Set the name to be `Key`.
+
+1. Set the value of `Key` to be the value copied from the Application Server in Step 4 of [Retrieve Existing Encryption Key][]:
+
+    1. Double click on the registry value `Key` to open the Edit dialog.
+    1. Set the value.
+    1. Click `OK`.
