FTPS / Implicit SSL

See more FTP Examples

Demonstrates how to connect using implicit SSL on port 990. The FTP component connects using SSL on port 990, which is the de-facto standard FTP SSL port. Not all FTP servers support implicit SSL. An alternative is to use AUTH SSL (also called AUTH TLS). Java
