HTTP vs HTTPSWhat is HTTP?An HTTP stands for Hypertext Transfer Protocol. The HTTP protocol provides communication between different communication systems. When the user makes an HTTP request on the browser, then the webserver sends the requested data to the user in the form of web pages. In short, we can say that the HTTP protocol allows us to transfer the data from the server to the client. An HTTP is an application layer protocol that comes above the TCP layer. It has provided some standard rules to the web browsers and servers, which they can use to communicate with each other. An HTTP is a stateless protocol as each transaction is executed separately without having any knowledge of the previous transactions, which means that once the transaction is completed between the web browser and the server, the connection gets lost. What is HTTPS?The full form of HTTPS is Hypertext Transfer Protocol Secure. The HTTP protocol does not provide the security of the data, while HTTP ensures the security of the data. Therefore, we can say that HTTPS is a secure version of the HTTP protocol. This protocol allows transferring the data in an encrypted form. The use of HTTPS protocol is mainly required where we need to enter the bank account details. The HTTPS protocol is mainly used where we require to enter the login credentials. In modern browsers such as chrome, both the protocols, i.e., HTTP and HTTPS, are marked differently. To provide encryption, HTTPS uses an encryption protocol known as Transport Layer Security, and officially, it is referred to as a Secure Sockets Layer (SSL). This protocol uses a mechanism known as asymmetric public key infrastructure, and it uses two different keys which are given below:
Main difference between the HTTP and HTTPSThe major difference between the HTTP and HTTPS is the SSL certificate. The HTTPS protocol is an extended version of the HTTP protocol with an additional feature of security. This additional feature of security is very important for those websites which transmit sensitive data such as credit card information. The HTTPS protocol is secured due to the SSL protocol. The SSL protocol encrypts the data which the client transmits to the server. If someone tries to steal the information which is being communicated between the client and the server, then he/she would not be able to understand due to the encryption. This is the main difference between the HTTP and HTTPS that the HTTP does not contain SSL, whereas the HTTPS contains SSL that provides secure communication between the client and the server. Which is better, HTTP or HTTPS?Till now, we read that the HTTPS is better than HTTP because it provides security. Sometimes our website does not contain an e-commerce page that requires sensitive data; in that case, we can switch to the HTTP protocol. Despite the security, HTTPS also provides SEO. So, we do need to put more effort into boosting our SEO. HTTP vs HTTPS performanceThe speed of HTTP is faster than the HTTPS as the HTTPS contains SSL protocol, while HTTPS does not contain an SSL protocol. This additional feature of SSL in HTTPS makes the page loading slower. Differences between HTTP and HTTPSThe following are the differences between the HTTP and HTTPS:
The HTTP protocol stands for Hypertext Transfer Protocol, whereas the HTTPS stands for Hypertext Transfer Protocol Secure.
The HTTP protocol is not secure protocol as it does not contain SSL (Secure Sockets Layer), which means that the data can be stolen when the data is transmitted from the client to the server. Whereas, the HTTPS protocol contains the SSL certificate that converts the data into an encrypted form, so no data can be stolen in this case as outsiders do not understand the encrypted text.
The HTTP transmits the data over port number 80, whereas the HTTPS transmits the data over 443 port number. Under the documentation issued by Tim Berners-Lee, he stated that "if the port number is not specified, then it will be considered as HTTP". When RFC 1340 was announced, then the IETF (Internet Engineering Task Force) provided port number 80 to the HTTP. When the new RFC was released in the year 1994, the HTTPS is assigned with a port number 443.
The HTTP protocol works on the application layer while the HTTPS protocol works on the transport layer. As we know that the responsibility of the transport layer is to move the data from the client to the server, and data security is a major concern. HTTPS operates in the transport layer, so it is wrapped with a security layer.
When we want our websites to have an HTTPS protocol, then we need to install the signed SSL certificate. The SSL certificates can be available for both free and paid service. The service can be chosen based on business needs. The HTTP does not contain any SSL certificates, so it does not decrypt the data, and the data is sent in the form of plain text.
The SEO advantages are provided to those websites that use HTTPS as GOOGLE gives the preferences to those websites that use HTTPS rather than the websites that use HTTP.
If we are running an online business, then it becomes necessary to have HTTPS. If we do not use the HTTPS in an online business, then the customers would not purchase as they are scared that their data can be stolen by the outsiders. Let's understand the differences in a tabular form.
