# Certificates

On the Certificates tab, you can manage trusted Transport Layer Security (TLS) certificates that are signed by your local Certificate Authority (CA) or an external CA to create a chain of trust.

The controller will use the TLS certificate for HTTPS to communicate securely with ToolsNet/ToolsTalk if encryption is turned on. If the ToolsNet/ToolsTalk server requires client validation, set up the certificate at the controller side and configure ToolsNet/ToolsTalk to trust the controller's certificate.
