How to choose the best free SSL Certificate to protect your website?
Website security and secure transactions through the website makes it right for customers to build trust which further enhances the conversion rate. Customers are destined to stay protected online and so online business websites and its transactions are to be protected from online shenanigans..
HTTPS would enhance the ranking in the SERP results. So installing an SSL certificate on your website, would improve website traffic, enhance protection fro hackers and boost customer trust and thereby increases rate of conversion.
There are a range of SSL certificates that are devised to protect types of businesses ranging from small to large scale. Choosing the right SSL certificate type would help you save your time.
- Some businesses need SSL just for encryption
- Some businesses require SSL to enhance security and business identity to ensure customers for their legitimacy.
There are three types of SSL Certificates
Extended Validation (EV) SSL Certificate – The Certificate Authority provides the SSL Certificate after strenuous and strict validation procedures.
The verification includes
- Authentication of the physical, legal and operational existence of the entity
- Validating, if the identity of the business entity matches right with the provided official records
- Validating the business entity if it is authorised to use domain specified in the EV SSL
- Validating if that the entity has properly authorized the issuance of the EV SSL
Organization Validation OV SSL Certificate – In this case, the Certificate Authority conducts vetting of the organization. The customers can get the details of the organization while clicking on the site seal and enhances trust
Domain Validated DV SSL Certificate – The certificate authority checks if the applicant is authorized and legitimate to use a definite domain name.
Types of SSL Certificates by Secured Domains
- Single-name SSL Certificates – This type of SSL Certificate equips to protect a single subdomain (hostname). For instance – It will protect www.abc.com and not mail.abc.com
- Wildcard SSL Certificates – This is one other type of SSL Certificate that is destined to protect a main domain and its supporting unlimited number of subdomains. With a single wildcard SSL certificate, both the main domain and its subdomains can be protected. This saves you time and money. For instance – It will protect www.example.com along with its mail.example.com and other such unlimited sub domains.
- Multi-Domain SSL Certificates – This type of certificate is provisioned to secure a variety of domains with a single certificate by means of SAN extension. Hence they are referred to as SAN certificates.
How to add SSL Certificate to a website?

- Take a back up of the installed SSL certificate & private key
Objectives of the SSL protocol
The key objectives of Secure Sockets Layer (SSL) protocol are-
- SSL authenticates participants in a communication session, at the client end and server end. This is done employing standard key cryptographic techniques, mainly public key encryption.
- SSL ensures, through encryption during a communication session, data integrity. Thus it becomes impossible to tamper with data in any way.
- Data privacy is ensured during transit, in a communication session. This helps prevent interception and thus whatever is communicated can be read only by the recipient.
Architecture of the SSL protocol
The SSL protocol has a stack-based architecture and comprises of a suite of protocols over TCP/IP. It’s thus often called the ‘SSL Protocol Stack’.
SSL Record Protocol, which is the first layer of the ‘SSL Protocol Stack’, ensures data security through encryption, plus data integrity. This layer is also responsible for the checking of data and the encapsulation of data with appropriate headers, for secure transmission under TCP protocol. Then there are the SSL Handshake Protocol, the SSL Change Cipher protocol and the SSL Alert Protocol. These three top layers of the ‘SSL Protocol Stack’ are responsible for establishing a secured connection with an application protocol like HTTP, session management, cryptographic parameter management and the secure transfer of SSL messages between the client and the server.
