Upload Certificate for HTTPS Connection
You can install a trusted certificate issued by a certification authority, such as TC TrustCenter,

A digital certificate is an electronic document that binds a public key with an identity, for
example, an organization or an user. The binding between a public key and the identity is done
by a signature. This signature can be self-signed or authenticated by a certification authority.

some web browsers display the following (or a similar) warning message in the address bar:
