How To make a secure connection

Protocol Summary

FTP No secure connection.
FTPS
(Explicit)
Explicit security requires that the FTP client issues a specific command to the FTP server after establishing a connection to establish the SSL link. The default FTP server port is used. This formal method is documented in RFC 2228.

FTPS
(Implicit)

Implicit security is a mechanism by which security is automatically turned on as soon as the FTP client makes a connection to an FTP server. In this case, the FTP server defines a specific port for the client (990) to be used for secure connections.

Note: Implicit is deprecated.
