What is a SSL Certificate? How does it works?

SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private. If you don’t have the SSL certificate, a secure connection cannot be established.
SSL Certificates contain the following information:

• Name of the holder
• Serial number and expiration date
• Copy of the certificate holder’s public key
• Digital Signature of the certificate-issuing authority

Why are SSL Certificates Important?

Here are some of the reasons to have SSL Certificates:

1. Encrypts Sensitive Information

Without a https connection, any information you send will not be automatically encrypted. As a result, a person can intercept sensitive information before it reaches its recipient. This information may include credit card information, usernames, and passwords. With a secure connection, the information becomes difficult to decipher for everyone except the intended recipient.

2. Protects You From Cyber-Criminals

Without encryption, prying eyes can intercept and read sensitive information. In certain cases, this may result in identity theft, hacked emails, hacked accounts, or personal information being leaked.

3. Builds Trust

With SSL certificates, your customers will see visuals, like lock icon and green address bar, that indicate a encrypted connection. In other words, this provides the visitor reassurance that any information they send or receive will be safe.
