The main difference between HTTP and HTTPS lies in the security features they offer. Here are the key differences between the two protocols: Encryption: HTTP messages are sent in plaintext, which means unauthorized parties can easily access and read them over the internet. In contrast, HTTPS transmits all data in encrypted form, ensuring that no third parties can intercept the data over the network.
Ports: HTTP uses port number 80 for communication, while HTTPS uses port number 443.
SSL Certificates: HTTPS requires SSL certificates for public-key encryption, which helps to secure the communication between the browser and the server. HTTP does not require any certificates.
Security: HTTP is considered unsecure, as it does not use encryption and can be easily intercepted. HTTPS is considered secure, as it uses encryption to protect information as it is being sent.
Search Ranking: HTTPS helps to improve search ranking, while HTTP does not have any impact on search ranking. In summary, HTTPS is a more secure version of the HTTP protocol, as it uses encryption and digital certificates to protect the data transmitted between a user's browser and a website. This makes HTTPS the preferred choice for modern websites, especially those that require the transmission of sensitive information, such as passwords or credit card numbers.
