Resolution:
At this time, secure FTP is not embedded in the BC framework. For the moment, none of the BC plugins offer support for Secure FTP out of the box except our EDI plugin.

Our BC-EDI implementation of Secure FTP creates a secure control and data connection (SSL) when an FTP connection is opened. The FTP server and the FTP client, in this case TIBCO BusinessConnect EDI Protocol, exchange certificates and create a secure, encrypted connection before sending or receiving data or FTP commands. Secure TP is supported only with custom FTP scripts by using the EDIFTPClient API. Secure FTP is not supported when an FTP connection goes over a proxy server.

As per our TIBCO BusinessConnect EDI Protocol Guide, Appendix B Secure FTP,

The following items are required:
Partners that need to do a secure FTP connection to a secure FTP server should get their partner's certificates, including the root certificates if any, used for SSL and load them into the Partner Identity pool of the trading partner.
The custom scripts should use the Secure FTP API. Use the Upload Scripts option for the FTP-Get inbound and FTP outbound transports to load the scripts. See FTP-Get Configuration and Using the FTP Transport Protocol  Outbound to see where the Upload Scripts option displays.

Please refer to our TIBCO BusinessConnect EDI Protocol Guide JavaDoc FTP API Reference for further details.

Do BusinessConnect or any of its plugins support Secure FTP?
