What Is an SSL Certificate and Why Your Website Needs It in 2026
In today’s digital world, online security is no longer optional—it’s essential. Every day, millions of internet users share sensitive information such as passwords, personal details, and payment data. Protecting this information is where an SSL Certificate plays a critical role.
An SSL Certificate (Secure Sockets Layer) is a security technology used to create a secure and encrypted connection between a web server and a user’s web browser. This encryption ensures that all data exchanged during online transactions remains private, protected, and safe from cyber threats.
At NXTWAT, a leading Web Development Company In bangalore and digital solutions provider in Bangalore, we integrate SSL security into every website we build—whether it’s affordable website design, mobile app development, web hosting in India, digital marketing, web application development, or enterprise software solutions.
What Is an SSL Certificate?
An SSL certificate is a digital certificate that:
- Encrypts data shared between a website and its visitors
- Prevents hackers from intercepting sensitive information
- Confirms the authenticity of a website
- Displays the HTTPS prefix and padlock symbol in the browser
Today, almost all secure internet transactions—online banking, e-commerce, login systems, and form submissions—depend on SSL technology.
Who Created SSL?
The SSL protocol was originally developed by Netscape to secure online communication. Although modern security now uses TLS (Transport Layer Security), the term SSL is still widely used to describe website encryption.
How Does an SSL Certificate Work?
Here’s a simplified step-by-step explanation of how SSL secures a website:
Step 1: Secure Page Request
The user’s web browser requests a secure page (HTTPS) from the website server.
Step 2: Certificate & Public Key Exchange
If the website has an SSL certificate installed, the server sends the certificate along with its public key to the browser.
Step 3: Certificate Verification
The browser checks:
- Whether the certificate belongs to the website
- Whether it is still valid
- Whether it was issued by a trusted Certificate Authority (CA)
If any check fails, the browser warns the user that the site is not secure.
Step 4: Encrypted Data Transfer
Once verified, the browser creates a symmetric session key, encrypts it using the server’s public key, and sends it back to the server.
Step 5: Secure Communication Begins
The server decrypts the session key using its private key. From this point onward, all data exchanged between the browser and server is encrypted using the symmetric key.
Step 6: Secure Content Delivery
The web server sends encrypted HTML pages and HTTP data, which the browser decrypts and displays securely to the user.
This process ensures complete data confidentiality and integrity.
What Information Does an SSL Certificate Contain?
A standard SSL certificate includes:
- Company or organization name
- Domain name
- Country, state, and city
- Certificate Authority (CA) details
- Certificate issue and expiration dates
This information helps browsers verify the identity and trustworthiness of the website.
