What port is TLS?

Published in Network Security 2 mins read

The standard port for TLS (Transport Layer Security), which is commonly used with HTTPS (HTTP Secure), is port 443.

TLS is a protocol that provides secure communication over a network. It's often used to encrypt web traffic, ensuring that data transmitted between a web server and a client (like a web browser) remains private and secure from eavesdropping or tampering.

Here's a breakdown of related information:

  • HTTPS (HTTP Secure): This is the secure version of HTTP, the protocol used for transmitting data over the web. HTTPS uses TLS or its predecessor, SSL (Secure Sockets Layer), to encrypt the communication.
  • Port 443: This is the standard port for HTTPS traffic. When a web browser connects to a website using HTTPS, it typically connects to the server on port 443.
  • TLS/SSL Certificates: These digital certificates are used to verify the identity of the server and establish a secure connection. They are crucial for the proper functioning of TLS/SSL.
  • HTTP (Hypertext Transfer Protocol): This is the unencrypted protocol for transmitting data over the web. It typically uses port 80.
Protocol Port Security Description
HTTP 80 Unsecured Standard protocol for web communication
HTTPS 443 Secured (TLS/SSL) Secure protocol for web communication, encrypts data

In summary, while TLS is a security protocol, the common port associated with its use, especially in web traffic through HTTPS, is port 443.
