What port protocols encrypt communications?

Several port protocols are designed to encrypt communications, including Secure Sockets Layer (SSL) and Transport Layer Security (TLS), commonly used with HTTPS (port 443) for secure web traffic. Other protocols include Secure Shell (SSH) on port 22 for secure remote access and File Transfer Protocol Secure (FTPS) on port 990 for secure file transfers. Additionally, internet Protocol Security (IPsec) can encrypt data at the network layer, often used in Virtual Private Networks (VPNs).
