There are many small site owners who don’t want to invest in SSL security because of their limited budgets.

Hence there are many Certificate Authorities who issue Free SSL Certificate who work on non-profit basis, to make internet a safer place. Freesslcertificate.org is one such provider who offers SSL for free.
What is an SSL?
In this digital world, where there are many prying eyes waiting to grab your personal data for satisfying their malicious intentions, SSL security is a boon in disguise.
SSL is an abbreviation of Secure Sockets Layer.
Their main function is to encrypt all sensitive information communicated between browsers and servers by using cryptographic algorithms; and hence this security protocol is also called cryptographic protocol.
Encryption in simple terms is the process of passing a coded message to the authorised person. Any unauthorised person cannot reach or read or decode the message.
This cryptographic method stops unauthorised interferences and protects sensitive information by transforming them into non-readable cipher text.
An example of encryption and decryption process is given below:
When SSL certificate is installed on a website, it shows two types of trust symbols.
1. HTTPS (Hyper Text Transfer Protocol Secure) instead of HTTP in the address bar
2. A green padlock in the URL
- Without SSL= http://example.com
With SSL = https://example.com
Customer’s check these trust symbols and are assured that the site is safe for making online financial transactions which in turn improves conversion rates. After Google made SSL security compulsory for all, SSL certificate helps boost SEO rankings too.
How does an SSL certificate work?
SSL certificates work like envelope seals who keep information safe within themselves.
The whole process of SSL certificates includes SSL handshakes, private key, public key, session key, encryption and decryption. It contains simple four step process.
- The first and foremost thing that a browser first checks when a user visits a website, whether the website has SSL security or not. If the website has SSL certificate installed than the process of SSL handshake starts.
- In SSL handshake, after the browser has checked the authenticity of the SSL certificate, the server creates public and private keys to handle encryption and decryption for secure communication.
- After the client checks the authenticity of the SSL certificate, the server and the client create a third key called the “session key” to secure communication.
- A secured connection is now created between client and server and they can communicate safely without unauthorised interferences.

Though their encryption level is the same as paid SSL certificates, they don’t provide any customer support help or warranty like paid SSL certificates. Even their issuance validity period is between 1 to 3 months whereas paid SSL can be issued for 1-2 years.
Mostly all SSL certificates are issued and signed by Certificate Authority, but some free SSL certificates are also Self Signed Certificates; wherein the user can sign the SSL certificate themselves and issue the same for their website.

This helps gain customer trust for company as well as website. Their strong encryption security is the best for medium businesses, governments and e-commerce industries that need to protect sensitive data against cyber-criminals.
- Extended Validation SSL – Though EV SSL is costly and takes more issuance time (1-3 days) than the previous two validations, it is worth the money because of its ample advantages. All the legal documents of the company are verified before issuance of EV SSL and hence it is said to be the highest form of security.
