A CA certificate is a digital certificate issued by a certificate authority (CA). The CA certificate allows valid and secure connections between Litmus Edge and other systems.

To create a valid and secure connection between Litmus Edge and Litmus Edge Manager, a custom CA certificate needs to be generated. To complete this specific task, see [Activate an Edge Device](docId\:WaO2YpJsg1_aFdXtODqxW) for details. 

To upload a custom CA certificate not related to validating communication between Litmus Edge and Litmus Edge Manager, follow the steps below.
