What port number is associated with HTTPS?

HTTPS, which stands for Hypertext Transfer Protocol Secure, is the protocol used to securely transmit data over the web. It employs encryption protocols such as SSL/TLS to protect the data exchanged between a user's web browser and the web server. The standard port number associated with HTTPS is 443. This is important for many reasons, including ensuring secure communication, protecting sensitive information, and enabling secure transactions online.

By using this specific port, web browsers and servers can establish a secure connection that is distinct from unsecured HTTP traffic, which typically operates on port 80. The use of different port numbers helps differentiate between secure and non-secure communications, which is crucial for maintaining security standards in web communications.
