What is FTP over SSL (FTPS)?
FTP over SSL (FTPS or FTP/SSL) is a file transfer protocol using FTP in conjunction with a secure SSL (Secure Socket Layer) layer to provide extra encryption. The server provides a signed SSL certificate. When you use FTPS, you can transfer files and also perform some simple file and directory commands such as listing files and changing directories.
Note: FTP over SSL for file transfer to/from Cornell servers should ONLY be used because it is required by an external client, such as a bank or government office. Most file transfers can be completed using either SFTP/SCP or WebDAV.
