When you are working online you can see the URLs some starting with http and some with https. What are these and what is the difference between them. Both of these are protocol which is designed to send information between computers over World Wide Web. We will discuss in detail about these two types of protocol.
What is HTTP
HTTP stands for Hypertext Transfer Protocol. It is a system to transfer and receive information between the client and server. HTTP uses TCP which stands for transmission control protocol to send and receive data over the web. The HTTP sends and receives images, videos and files over the internet but not in encrypted form.
The lifetime of the HTTP connection corresponds to a single request response sequence. It treats every request as brand new. The HTTP pages are saved in your computer and internet caches and that’s why the pages are loaded much faster. As long as we are not having bank transactions, online purchases or sending some important and secure file this protocol works fine. But to perform secure task you need HTTPS.
What is HTTPS
HTTPS stands for Hypertext Transfer Protocol over SSL. SSL is Secure Socket Layer and everything we send over HTTPS is in encrypted form. The other user cannot read the data you have sent or you received. Whenever we connect to the web via HTTPS the website encrypts the session with the digital certificate. SSL uses cryptographic system for the server and browser for encrypting data between the two. It is mostly used for login pages, bank transactions websites and other data sensitive sites.
Difference between HTTP and HTTPS
There are some differences between the two,
- HTTP data is unsecured whereas HTTPS data is encrypted and totally secured.
- No certificate validation required in HTTP whereas HTTPS has SSL Digital Certificate.
- HTTP operates at application layer whereas HTTPS operates on transport layer.
- HTTP uses port 80 for communication, on the other hand HTTPS uses port 443 for communication.
