Reference: Overview of Beyond FTP
Beyond FTP supports both client and server certificates when operating secure FTP connections. A client certificate would be provided for the address of a remote FTP server, and would be used for every connection from Beyond FTP to that server. Beyond FTP includes a default client certificate.
A server certificate is used only by the FTP server included in the Standard Edition and Enterprise Edition versions of the Beyond FTP server product. The FTP server supports SSL/TLS connections when a server certificate is provided. Beyond FTP includes a default server certificate.
Customer certificates can be supplied in place of either default certificate. They must include private keys.
