About SSL Certificates

Introduction to SSL Certificates

SSL (Secure Sockets Layer) certificates are an essential component of secure internet communication. They serve two primary purposes: encrypting data transmitted between a user's browser and a web server and verifying the authenticity of a website. SSL has evolved over time, and the term is now commonly used interchangeably with TLS (Transport Layer Security), which is a more secure and updated version of SSL.

Why SSL Certificates Matter

In today's digital age, where cyber threats are increasingly sophisticated, SSL certificates play a crucial role in ensuring online safety and trustworthiness. Here are the key reasons why they are vital:

How SSL Certificates Work

SSL certificates rely on a technology called public key infrastructure (PKI). PKI uses a pair of cryptographic keys: a public key and a private key. The public key is included in the SSL certificate and is used to encrypt data, while the private key is kept secret and is used to decrypt it. Here's a simplified overview of the process:

  1. When a user visits a website with SSL, the browser checks the validity of the SSL certificate and establishes a secure connection using the public key.
  2. The server and browser perform a "handshake" to agree on an encryption method and generate a session key for encrypting data.
  3. All subsequent data exchanged between the browser and server is encrypted using the session key, ensuring confidentiality and security.

Types of SSL Certificates

There are several types of SSL certificates to suit different needs:
