Starting with v15 it is now possible to replace the private key and certificate used for Encrypted Client-Server Communication.

Default key.pem and cert.pem files are provided with 4D. Although, for a higher level of security, we strongly recommend that you replace these files with your own certificates.

The corresponding files are:

• key.pem: document containing the private encryption key
• cert.pem: document containing the signed certificate.

These files are located in the Resources subfolder of the 4D Server and 4D applications.

These files must be present on the server machine and on each remote machine.
