Self-signed root certificates can be used for simple setups involving a single MobiLink or database server.
Use enterprise level certificate chains or commercial certificate authorities if you require multiple server identity files. Certificate authorities provide extensibility and a higher level of certificate integrity with dedicated facilities to store root private keys.
For more information about setting up certificate chains, see Certificate chains.
Certificate For server authentication certificates, the self-signed certificate is distributed to clients. It is an electronic document including identity information, the public key of the server, and a self-signed digital signature.
Identity file For server authentication certificates, the identity file is stored securely with a MobiLink or database server. It is a combination of the self-signed certificate (that is distributed to clients) and the corresponding private key. The private key gives the MobiLink or database server the ability to decrypt messages sent by the client in the initial handshake.
