What is SSL?
Firstly, if you have ever noticed the URLs of a website, they either show HTTPS or HTTP
As you can see the only difference between the two is ‘S’. HTTPS indicates that the website is more secured as the website has taken the SSL certificate. Using the normal HTTP protocol means the information on your website is not secure.
SSL stands for Secure Sockets Layer which helps to provide a secure transport connection between applications (e.g. a web server and a browser).
In other words, it is a layer of protection for your documents online. The extra layer of security is required for personal and sensitive data. If you don’t add that layer of authentication, hackers can access your information from your web server, e-mail, and website.
SSL certificates ensure consumers that their personal information is being handled safely and efficiently, giving them peace of mind when exchanging personal information on the internet.
Who Needs an SSL Certificate?
SSL Certificates are commonly used for people who share confidential data over the internet. Your user name or passport number, as well as any other information that needs to be kept secret, are examples of sensitive data.
SSL consists of two protocols :
- Handshake Protocol – It allows server and client to authenticate, negotiate an encryption algorithm and cryptographic keys.
- Record Protocol – It allows the transfer of data securely between web browser and server
Why We Use SSL Certificate?
- It protects data through Encryption
- Confirms your identity
- Helps in Avoiding “Non-Secure” Warning Message
Types of SSL Certificate
- Domain Validated (DV) SSL Certificate – It is perfect for securing blogs, personal websites, and online portfolios.
- Organization Validated (OV) SSL Certificate – It is necessary for e-commerce websites and medium-sized companies. Authenticate business identity and require paperwork. You can obtain one in a few days.
- Extended Validated (EV) SSL Certificate – EV certs require extensive validation and take a bit longer to obtain; however, the wait is more than worth it.
- Wildcard SSL Certificate – It helps to secure the main domain and all its sub-domains under a single SSL installation.
- Multi-Domain SSL Certificate – It helps to secure multiple domains and sometimes subdomains under a single certificate.
