What Is a Secure Socket Layer?

Secure Socket Layer (SSL) is a cryptographic protocol that ensures secure communication between web browsers and servers by encrypting data transmitted over the internet, preventing unauthorized access, interception, or tampering of sensitive information, such as personal data, payment details, and login credentials. 

How is Secure Socket Layer Useful?

SSL certificates play a critical role in web security and data privacy by providing cryptographic keys and digital signatures to authenticate web servers and encrypt data transmissions. This ensures confidentiality, integrity, and authenticity of online interactions and transactions for users and organizations. By implementing SSL encryption and obtaining SSL certificates, websites and web applications can enhance trust, credibility, and compliance with privacy regulations, such as the Payment Card Industry Data Security Standard (PCI DSS), General Data Protection Regulation (GDPR), and California Consumer Privacy Act (CCPA), to safeguard sensitive information and build customer confidence in online experiences

Secure Socket Layer In Academia 

In academia, SSL encryption is studied within the fields of computer security, network protocols, and information technology (Imic studies on SSL also explore its vulnerabilities, security threats, and encryption algorithms, as well as best practices for SSL deployment, certificate management, and security hygiene to mitigate risks and ensure robust protection against cyber-attacks and data breaches in the evolving threat landscape of the digital economy.

Also, learn about SSL certificates.

A secure sockets layer (SSL) certificate refers to a file hosted within the webpage’s origin server, which holds the data that browsers access when you are viewing and interacting with the page. The certificate may be self-signed or signed (issued) by a third party.

Frequently Asked Questions On Secure Socket Layer

What is SSL needed for?

SSL is a type of encryption protocol that secures data between browsers and servers so it can’t be intercepted. This makes it impossible for hackers to read customer information. Ultimately, SSL certificates create a safer website experience for businesses and customers.


How does SSL work between two servers?

The client generates a random symmetric key and encrypts it using server’s public key. The client and server now both know the symmetric key and can use the SSL encryption process to encrypt and decrypt the information contained in the client request and the server response.


What is an example of SSL?

One example of sensitive data protected by SSL is financial information, such as credit card numbers. Other examples include User login credentials. Personally identifiable information (PII).
