FTP: Link

File Transfer Protocol (FTP) is a standard network protocol used to transfer files from one host to another host over a TCP-based network, such as the Internet. It is often used to upload web pages and other documents from a private development machine to a public web-hosting server. 

TLS/SSL:Link

The TLS protocol allows client-server applications to communicate across a network in a way designed to prevent eavesdropping and tampering.
