FTP over SSL Microsoft Docs. Overview. The lt ssl element specifies the FTP over Secure Sockets Layer SSL settings for the FTP service FTP over SSL was first introduced for IIS 7 in FTP 7. Unlike using HTTP over SSL, which requires a separate port and connection for secure HTTPS communication, secure FTP communication occurs on the same port as non secure communication. FTP 7 supports two different forms of FTP over SSL Explicit FTPS By default, FTP sites and clients use port 2. In a typical FTP request, an FTP client client will connect to an FTP site over the control channel, and then the client can negotiate SSLTLS with the server for either the control channel or the data channel. When you are using FTP 7, you are using Explicit SSL if you enable FTPS and you assign the FTP site to any port other than port 9. Implicit FTPS Implicit FTPS is an older form of FTP over SSL that is still supported by FTP 7. PowerTCP SSH and SFTP sample applications including source code. With Implicit FTPS, an SSL handshake must be negotiated before any FTP commands can be sent by the client. In addition, even though Explicit FTPS allows the client to arbitrarily decide whether to use SSL, Implicit FTPS requires that the entire FTP session must be encrypted. When you are using FTP 7, you are using Implicit SSL if you enable FTPS and you assign the FTP site to port 9. Depending on the security options that you configure in the control. Channel. Policy and data. Channel. Policy attributes, an FTP client may switch between secure and non secure multiple times in a single Explicit FTPS session.
