Which port is designated for HTTPS traffic?

The designated port for HTTPS traffic is 443. HTTPS, which stands for Hypertext Transfer Protocol Secure, is the secure version of HTTP. This protocol encrypts the data exchanged between a web browser and a web server, ensuring that the communication remains private and protected from eavesdropping or tampering.

Port 443 is specifically assigned for secure web communication, allowing encrypted connections. When a user accesses a website using HTTPS, their browser communicates with the server through this port, providing a secure session.

In contrast, port 80 is typically used for standard, unencrypted HTTP traffic. Port 25 is commonly designated for SMTP (Simple Mail Transfer Protocol), which is used for sending emails. Port 8080 is often used as an alternative to port 80 for HTTP traffic, particularly in development environments or for proxy servers, but it does not specifically pertain to HTTPS. Thus, the designation of port 443 for HTTPS is fundamental for secure web communication.
