Hello Friends, In this article we will learn what is SSl Certificate & How it works? Security is a big deal to everyone doing business on the web. Have you ever noticed that some web addresses begin with http:// & others start with https://. in this case S word indicates that the web address has SSl security. SSL stands for Secure Sockets Layer.
The formation of SSl is invented by NETSCAP Communications in the year of 1994 to secure communications between clients and server applications over an unprotected network.
Secure Sockets Layer (SSL) is a standard security technology for establishing an encrypted link between a server and a client—typically a web server (website) and a browser. SSL certificates have a key pair: a public and a private key. These keys work together to establish an encrypted connection.
It technology the keeps sensitive information like Credit Card, Social security numbers, Usernames & Passwords out of the hands the cyber crooks.
If you don’t have a trusted SSl Certificate for you website it will be show a labeled “Not Secure” on Web Browsers just before the web address. From July 2018 Google Chrome has also decided to start showing a “Not Secure” sign in the address bar of the web browser for all the websites that have not installed an Valid SSl certificate.
How does SSL Certificate Work?
When a browser attempts to access a website that is secured by SSL, the browser and the web server establish an SSL connection using a process called an “SSL Handshake”.
In earlier days protocol was designed which was the name does “Hyper Text Transfer Protocol” (HTTP) a simple way to communicate from browser to the web server. At it’s most basic, it allows for the communication between different systems.
It’s most commonly used to transfer data from a web server to a browser in order to allow users to view web pages. It’s the protocol that was used for basically all early websites.
The problem with the regular HTTP protocol is that the information that flows from server to browser is not encrypted, which means it can be easily stolen. But now This Protocol (HTTP) is modified with the name of (HTTPS) “Hyper Text Transfer Protocol Secure”.
Here S word indicates that the web address has SSL Security (secure sockets layer) certificate, which helps create a secure encrypted connection between the server and the browser, thereby protecting potentially sensitive information from being stolen as its transferred between the server and the browser.
How Encryption Works in Details:
The complete concept of Secure Sockets Layer is based on the RSA (Rivest-Shamir-Adleman) algorithm. RSA is an algorithm used by modern computers to encrypt and decrypt messages where every single SSL certificate has a public key and a private key. Public key is used to encrypt information and Private key is used to decrypt the information.
When your browser connects to a secure domain, the server passes the public key to the browser to perform the encryption. Thus, Public key is give to all while the private key (used for decryption) is kept secret. On the time of Secure Communication browser encrypts the message using the public key and sends it to the server.
The message is dcrypt on the server side using the private key. Let’s learn SSL in a very simple words: Suppose you do a payment online where you fill your personal sensitive information like your Credit card number, Email ID, Username & Password.
Such information you don’t want to tell to others. But if you give this kind of information on such website which is running over http:// like http://www.example.com in this case this information is in normal letters & even not encrypt & it can be stolen by cyber crooks because such websites are not using SSl Certificate.
On the other hand if you give this kind of information on such website which is running over https:// like https://www.example.com in this case this information is fully encrypted & it can not be stolen & you can make a secure payment because such websites are using SSl Certificate.
Do i need an SSl Certificate?
If your website doesn’t collect sensitive information from visitors, like credit cards, Debit cards, Username, Passwords or social security numbers, then in this condition you may not have needed a SSL certificate in the past. However, a SSL Certificate can help you increase the traffic on your website.
With the new browser notices, it’s now important to ensure every website or blog has a SSL certificate and is to be loaded via (HTTPS) “Hyper Text Transfer Protocol Secure” instead of (HTTP) “Hyper Text Transfer Protocol”.
What is advantages of SSl Certificate?
There are lots of advantages if your website or blog has a SSl Certificate. Here are 4 major benefits of SSl Certificate:
1. Strongest Encryption to Secure Information:
The major purpose of an SSL certificate is to encrypt information so that it can only be read and understood by the intended parties. All information about your website or blog is encrypted. All the information transferred over an SSL connection is encrypted and there is no way an interceptor could decipher your information.
When the credit card data and other private information will travel between the web server and users’ browser, the site will be secured with robust encryption that left no place for hackers to sniff transmitting information.
2. Boost Ranking in Search Results:
Secure website with SSL Certificate increases the rank of google search. If your website is secured with SSL certificate and web URL starts with a secure HTTPS protocol, then you will get the ranking advantage in search engines. If your website’s sitemap is not being submitted, installing the SSL certificate easily becomes sitemap submit.
3. Secure Payments to Experience Safe Shopping:
This is very important for the E commerce website because the E commerce website is mostly do online payment. So it’s also mandatory for a business site to have an SSL certificate.
4. Increase visitor loyalty to your site:
If your site uses account logins with personal data, then you should have an SSL certificate in place anyway. Visitors who know their information is protected are more likely to keep coming back.
By reading this article, I believe you now have enough information about SSl Cerificate & when you’re protected by SSL while on other folks’ websites and how to protect visitors to your own websites. Hopefully you could answer the question: Is an SSL certificate mandatory?
Didn’t switch to SSL yet? Then now it’s time to take action. Sooner or later we all have to install SSL Certificate on your Website or Blog. For installing free SSL Certificate in your Website read below article-
