When your application makes an HTTPS request, the server's certificate must be issued by a CA on this list for the connection to succeed. You will typically not need to consult this list. However, it can be a valuable diagnostic tool if you are experiencing platform-specific network connection failures that you suspect are related to a TLS handshake error. ## Supported Root Authorities | | | | | :----------------------------------- | :---------------------------------------------------------- | :----------------------------------------------------------- | | AAA Certificate Services | emSign Root CA -
