- HTTPS Server Authentication is preferably used in combination with Client Authentication (mutual authentication) as this allows a secure configuration without use of passwords.
- The purpose of Server Authentication is to secure the identity of an HTTP server and to encrypt the communication between client and server.
- The purpose of Client Authentication is to prove the identity of a client. Without proof of identity any HTTP client could perform a man-in-the-middle attack e.g. by pretending to be a Controller that connects to an Agent.
- Consider the communication scheme between JS7 components as explained from the JS7 - System Architecture:
- User browsers acting as HTTPS clients establish connections to JOC Cockpit as an HTTPS server.
- JOC Cockpit acting as an HTTPS client establishes connections to Controllers Controller instances acting as HTTPS servers.
- Controllers Controller instances acting as HTTPS clients establish connections to Agents acting as HTTPS servers.
- We recommend to apply mutual authentication, however, there might be reasons why use of Client Authentication is not an immediate option, for example:
- Use of a wildcard certificate for Server Authentication leverages the effort for certificate management. At the same time such certificates cannot be used for Client Authentication.
- Should mutual authentication not be an immediate option then the recommendations from this article for the handling use of passwords apply.

- In this example
js7_devis the Controller ID used by a solo Controller or by a Controller Cluster. A Controller is assigned a unique Controller ID during initial operationinstallation. The Controller ID cannot be changed unless the Controller's journal is reset. - The
passwordfor the Controller ID in the Agent configuration is the same as stated with the Controller configuration.- The password has to be preceded with "plain:" if a plain text password is used.
- The password has to be preceded with "sha512" if a password hashed with this algorithm is used
- There are a number of ways how to create sha512 hash values from passwords.
- A possible solution includes to use:
openssl passwd -6
