Hello everyone in this article we’re going to talk about HTTP secure,HTTP,TLS and SSL.

What is HTTP?

HTTP stands for hypertext Transfer Protocol now this is probably the most widely used protocol in the world today HTTP is the protocol that is used for viewing web pages on the Internet so when you type in a web address like google.com you’ll notice that HTTP is automatically added at the beginning of the web address and this indicates thatyou are now using HTTP to retrieve this web page now in standard HTTP all the information is sent in clear text so all the information that is exchanged between your computer and that web server which includes any text that you type on that website that information is transferred over the public Internet and because it’s transferred in clear text it’s vulnerable to anybody who wants it such as hackers now normally this would not be a big deal if you were just browsing regular websites and no sensitive data such as passwords or credit card information are being used but if you were to type in personal sensitive data like your name address phone number passwords or credit card information that sensitive data goes from your computer and then it has to travel across the public Internet to get to that web server and this makes your data vulnerable because a hacker that somewhere on the Internet can listen in as that data is being transferred and steal your information so as you can see this hacker is stealing personal information as its traveling over the Internet so he has a name phone number address credit card numbers and so on so this is a problem as far as security and this is why HTTPS was developed.

What is HTTPS?

HTTPS stands for secure hypertext Transfer Protocol and this is HTTP with a security feature secure HTTP encrypts the data that being retrieved by HTTP it ensures that all the data that’s being transferred over the internet between computers and  servers is secure by making the data impossible to read and it does this by using encryption algorithms to scramble the data that’s being transferred so for example if you were to go to a website that requires you to enter personal information such as passwords or credit card numbers you will notice that an “S” will be added to the HTTP in the web address and this s indicates that you are now using secure HTTP and have entered a secure website where sensitive data is going to be passed and that data is going to be protected and in addition to the s being added a lot of web browsers will also show a padlock symbol in the address bar to indicate that secure HTTP is being used so by using secure HTTP all the data which includes anything that you type is no longer sent in clear text it’s scrambled in an unreadable form as it travels across the internet so if a hacker were to try and steal your information he would get a bunch of meaningless data because the data is encrypted and the hacker would not be able to crack the encryption to unscramble the data now secure HTTP protects the data by using one of two protocols and one of these protocols is SSL.

What is SSL?

SSL or secure Sockets Layer is a protocol that’s used to ensure security on the Internet it uses public key encryption to secure data so basically this is how SSL works so when a computer connects to a website that’s using SSL the computer’s web browser will ask the website to identify itself then the web server will send the computer a copy of its SSL certificate an SSL certificate is a small digital certificate that is used to authenticate the identity of a website basically it’s used to let your computer know that the website you’re visiting is trustworthy so then the computer’s browser will check to make sure that it trusts the certificate and if it does it will send a message to the web server then after the web server will respond back with an acknowledgment so when SSL session can proceed then after all these steps are complete encrypted data can now be exchanged between your computer and the web server and the other protocol that secure HTTP can use is called TLS.

What is TLS?

TLS or transport layer security is the latest industry standard cryptographic protocol it is the successor to SSL and it’s based on the same specifications and like SSL it also authenticates the server client and encrypts the data it’s also important to point out that a lot of websites are now using secure HTTP by default on their websites regardless if sensitive data is going to be exchanged or not and a lot of this has to do with Google because Google is now flagging websites as not secure if they are not protected with SSL and if a website is not SSL protected Google will penalize that website in their search rankings so that’s why now if you go to any major website you’ll notice that secure HTTPS is being used rather than standard HTTP
