The basic difference between Http and https is that https is more secured then Http. Before comparing the Http and Https we want to give some introduction of HTTP and HTTPS.
What is HTTP?
HTTP stands for “HYPERTEXT TRANSFER PROTOCOL” and use to view the web page. When you enter http:// in your address bar in front of the domain for example, “https://aticleworld.com/“. It tells the browser to connect over HTTP. HTTP uses TCP (Transmission Control Protocol), generally over port 80, to send and receive data packets over the web.
The client sends a request message to an HTTP server that hosts a website. If everything will be ok, then the response message contains completion status information, such as HTTP/1.1 200 OK.
The problem with HTTP protocol is that connection between server and client is not secured and data transferred between in plain text format. So there are chances that anybody hacks your data or terminate your connection.
What is HTTPS?
HTTPS stands for “Hypertext Transfer Protocol Secure” (referred to as HTTP over TLS/SSL). I also use to view the web page. When you enter https:// in your address bar in front of the domain for example, “https://aticleworld.com/”.It tells the browser to connect over HTTPS. HTTPS uses TCP (Transmission Control Protocol), generally over port 443 to send and receive data packets over the web.
HTTPS transmits data using an encrypted connection. The hashing algorithm and encryption algorithm negotiate at the time of handshaking while establishing the connection.
If we are talking about the core concept of https, then it basically uses a public key which is then decrypted on the recipient side. The public key is deployed on the server, and included in an SSL certificate. The certificates are cryptographically signed by a Certificate Authority (CA), and each browser has a list of CAs it implicitly trusts.
Now let see the difference between HTTP and HTTPS
|
HTTP |
HTTPS |
| HTTP stands for hypertext transfer protocol. | HTTP stands for hypertext transfer protocol with secure. |
| HTTP URL in your browser’s address bar is http:// | HTTPS URL in your browser’s address bar is https:// |
| HTTP is unsecured. | HTTPS is secured. |
| It uses port 80 by default | It uses port 443 by default. |
| HTTP operates at the application layer | HTTPS operates at the transport layer |
| No SSL certificates are required for HTTP | SSL certificate required for HTTPS. SSL certificate could be self-signed or signed by a CA. |
| HTTP does not scramble the data to be transmitted. That’s why there is a higher chance that transmitted information is available to hackers. | HTTPS scrambles the data before transmission. At the receiver end, it descrambles to recover the original data. Therefore, the transmitted information is secure which can’t be hacked. |
| HTTP doesn’t require domain validation | HTTPS requires at least domain validation and certain certificates even require legal document validation. |
| It operates at the TCP/IP level. | HTTPS does not have any separate protocol. It operates using HTTP but uses an encrypted TLS/SSL connection. |
| No encryption in HTTP | In HTTPS data is encrypted before sending. |
| HTTP does not improve search rankings. | HTTPS helps to improve search ranking. Now Google is penalizing the HTTP websites |
| HTTP Fast as compare to HTTPS. | Slower than HTTP. |
| Vulnerable to hackers | It Is highly secure as the data is encrypted before it is seen across a network. |
