FTPS, also known as FTP Secure is a File Transfer Protocol with SSL Security. Primarily, it enables delivering standard FTP communication on top of an SSL-based security connection. FTPS is an extension to the FTP protocol that combines SSL (Secure Socket Layer)/ TLS (Transport Layer Security) based mechanisms on a standard FTP connection. There are two different forms to deliver FTPS:
Explicit FTPS — Selected components or parts for communication are encrypted.
Implicit FTPS — All communications are encrypted.
