The Server Settings tab provides general SFTP server settings, as well as a way to select and generate the server certificate.
Here an X.509 certificate can be selected to provide the identity of the server and support SSH connections. Certificates stored in the Windows User/Machine certificate stores as well as certificates stored in .PFX, .PEM, or .PPK files can be used.
By default a test certificate is already configured. Before moving to production it is strongly recommended that the default test certificate is changed.
