FTPS: File Transfer Protocol over SSL. FTPS is similar to the standard FTP but
because it operates over an encrypted link (SSL), it is a more secure way to
transfer files over the Internet. The NSS supports Explicit FTPS (versus Implicit
FTPS). Explicit FTPS is named for the command issued to indicate that TLS
security should be used. This is the preferred method according to the RFC
defining FTP over TLS. The client connects to the server port 21 and starts an
unencrypted FTP session as normal, but requests that TLS security be used and
performs the appropriate handshake before sending any sensitive data.
