Have you noticed HTTP: // or HTTPS: // while browsing a website in the address bar of a browser? These are both internet protocols. If none of these are present, most likely, it is HTTP: //. At some point in your mind, the question must have been that what are they, how do they work, and what is the difference between HTTP and HTTPS. In this article, we have tried to give complete information about HTTP and HTTPS.
What is HTTP?
HTTP is an abbreviation for Hypertext Transfer Protocol. It allows World Wide Web users to transfer information such as photos, text, videos, music, and other files to web pages. HTTP is basically used to access and read HTML pages. HTTP has been the most commonly used protocol for data transfer on the web. This protocol was originally used for all early websites.
What is HTTPS?
The full form of HTTPS is Hypertext Transfer Protocol Secure. The problem with the HTTP protocol is that the information flowing from the server to the browser is not encrypted, which means that it can be easily stolen. The HTTPS protocol encrypts it using an SSL (Secure Socket Layer) certificate, which helps to create a secure encrypted connection between the server and the browser, thereby secure to stealing sensitive information from being transferred between the server and the browser.
Earlier HTTPS connections were used only for online financial transactions. But, in recent years, almost all types of websites have started using HTTPS connections to provide secure communication. Websites using HTTPS have a unique digital certificate, which is purchased from some certificate authority companies such as GeoTrust, Managing Encrypt, etc.
HTTP Error Codes
During Internet surfing, you must have encountered an error on your browser at some time. Sometimes it becomes a big problem for us, especially when we do not understand the reason behind these errors.
To understand the errors related to HTTP, some error codes have been created which are also known as HTTP status codes, through which we help to understand the reason behind the error.
Some common error codes associated with HTTP are as follows:
400 Bad File Request: This error code appears when our URL is wrong such as using capital letters instead of small, the mistake in typing symbols, etc.
401 Unauthorized: This error can occur due to entering the wrong password.
403 Forbidden / Access Denied: When you are opening a page whose permission you do not have, then in this case this response code can be seen.
404 File Not Found: This is the most common error. When you are requesting a file or document that is not available on the server, either deleted or moved to another location, then in such a situation a 404 error occurs.
408 Request Timeout: This error occurs mostly when the speed of the server is slow or the size of the requested file is high.
500 Internal Error: When there is some problem in the configuration of the server, then there is difficulty in accessing the file and the status code of internal error appears.
503 Service Unavailable: This type of error can occur when there is a problem with the Internet connection, the server is busy, or the site has moved to another address.
What is the Difference Between HTTP and HTTPS?
|Invention||This protocol was invented by Sir Timothy John.||This protocol was invented by Netscape Corporation for its Navigator browser.|
|Starting||HTTP URLs begin with http: //||HTTPs URLs begin with https: //|
|Protocol||It uses the TCP / IP protocol.||HTTPS does not have a separate protocol. It uses HTTP, but uses encrypted TLS / SSL connections.|
|Port||It uses port 80 by default.||This was the use of port 443 by default.|
|Security||This is less secure as data can be vulnerable to hackers.||The hack is designed to prevent hackers from accessing important information. It is safe against such attacks.|
|Used||Mostly used in such blogs.||Mostly used in websites that use online payments such as banks and e-commerce but recently many website using this protocol`|
|Data Encryption||HTTP does not encrypt data when transferring data. Therefore hackers have an opportunity to access information.||HTTPS encrypts data before data is transferred. Therefore the information in HTTPS is protected.|
|SSL Certificate||The HTTP website does not require SSL.||HTTPS requires SSL certificate.|
|Google Ranking||HTTP does not improve ranking in Google.||HTTPS helps improve ranking in Google. In 2014, Google started using HTTPS as a high-ranking signal.|
|Speed||faster than https.||In HTTPS, SSL has an additional phase. This additional step slightly reduces the page load speed of the website.|
|Hacking||Hacking is more likely.||There is very little chance of hacking.|
|Believe||Less trust in customers as they are at risk of security breach and sensitive information may be leaked.||Establishes trust with customers because they know that their sensitive information such as browsing history, account details, etc. is safe.|
|Use of AMP||We cannot use AMP (Accelerated mobile pages) with HTTP.||If you want to use Google AMP, then HTTPS is a must.|
Advantages of HTTPS or Secure Server
It allows users to conduct secure e-commerce transactions such as online banking.
SSL technology protects any user and builds trust.
An independent authority verifies the identity of the owner of the certificate. Therefore each SSL certificate contains unique, authentic information about the owner.
Google wants to send its users to secure sites and this makes HTTPS connections a ranking signal. This means that a website with HTTPS is going to be ranked higher than an HTTP website.
