difference http and https

What are HTTP and HTTPS?

Whether it’s HTTP or HTTPS, both are protocols build to transfer information between computers over WWW (World Wide Web). The main difference is that when “S” is attached to the “HTTP.”
HTTP (HyperText Transfer Protocol) does the same thing as HTTPS, like conveying information like document, file, image, video between computers over the web, but not in an encrypted format it becomes vulnerable to attacks occur over the web. So, for this, HTTPS is introduced.


HTTP stands for Hypertext Transfer Protocol. HTTP is a client-server protocol in that two devices communicates using a reliable, connection-oriented transport service such as the TCP.
It is platform-independent, which allows straight cross-platform porting.
As I said earlier, it has some security concerns, like privacy is not there, anyone can see your content. Integrity is not there, so someone can easily alter the content. HTTP is an insecure protocol because it has no encryption methods.


HTTPS is a Hypertext Transfer Protocol over Secure Socket Layer. HTTPS encrypts an HTTP message before transmission and decrypts a message after arrival. By default, HTTPS uses 443 port, whereas HTTP uses a port of 80.
SSL transactions are negotiated using a key-based encryption algorithm between the client and the server. This key is usually either 40 or 128 bits in strength, though a higher number of bits indicates a more secured transaction.
HTTPS or SSL connections are mandatory if you have your online store or do any financial transactions using your credit cards. It’ll very useful if you are sharing some sensitive information on the web.

In Computer Networking, HTTP works on Port 80, and HTTPS works on Port 443.

As HTTP protocol is not using any security mechanism to encrypt the user information, Technology giants such as Google, Microsoft, Mozilla, etc., are considering HTTP login connection as unsecured and displaying the error.

That HTTPS is a secured version, it encrypts the information using the SSL certificate (made up of a strong and complex hashing function known as SHA-2); hence, the info transforms from client to server, no other person or robot can access, breach or temper it.

Advantages of HTTPS/SSL

  • SSL Encrypts Sensitive Information

  • SSL Provides Trust
  • Necessary for Accepting Payments
  • Guards Against Phishing
  • Improves Customer Trust
  • Protect your own information

SEO Advantages of Switching to HTTPS

  • Increased rankings
