HTTPS listens on port 443.
HTTPS, or Hypertext Transfer Protocol Secure, is an extension of HTTP and uses port 443 by default for secure communication over the internet. Port 443 is designated for secure web traffic, ensuring that data exchanged between a user's web browser and a web server is encrypted. This prevents unauthorized access and eavesdropping.
For example, when you access a website like https://www.example.com, your browser connects to the server on port 443 to establish a secure connection. This is different from HTTP, which uses port 80 for unencrypted communication.
In the context of cloud services, platforms like Tencent Cloud offer services that support HTTPS, ensuring secure data transmission. For instance, Tencent Cloud's Cloud Load Balancer can be configured to handle HTTPS traffic on port 443, providing both load distribution and security features for your web applications.
