What Are the Differences Between HTTPS and HTTP?

Differences Between HTTPS and HTTP

Hypertext Transfer Protocol (HTTP) was commonly used for a long time. HTTP does not encrypt data in transmit, so confidential information, such as passwords, accounts, and transaction records, transmitted over HTTP is plaintext and easy to be leaked, stolen, or tampered with anytime. HTTP is insecure for transmitting private information.

Based on the Secure Sockets Layer (SSL) protocol, Hypertext Transfer Protocol Secure (HTTPS) activates an SSL encrypted channel between a web browser and a website server for a user to visit the website where an SSL certificate has been installed. The channel allows high-strength bidirectional encrypted transmission to prevent leakage or tampering of the data being transmitted. Simply put, HTTPS is HTTP plus SSL or a secure version of HTTP.

How Do I Change the Website Protocol from HTTP to HTTPS?

If you want to implement HTTPS for a website, you can purchase an SSL certificate and deploy it on the server corresponding to the website.

After an SSL certificate is deployed on a server, HTTPS is enabled on the server. The server uses HTTPS to establish encrypted links to the client, ensuring data transmission security.
