SSL certificates are essential for securing data transmission between a server and a client. They enable HTTPS, which encrypts information and ensures data integrity. Below is a guide to understanding and implementing SSL certificates.

📌 Key Concepts

  • SSL/TLS Protocol: A cryptographic protocol that provides communication security over a computer network.
  • Public Key Infrastructure (PKI): A framework that manages digital certificates and public-key encryption.
  • Certificate Authorities (CAs): Trusted entities that issue SSL certificates to verify identity.

🛠 How to Configure SSL Certificates

  1. Generate a CSR (Certificate Signing Request)
    Use tools like OpenSSL to create a CSR file containing your public key and domain information.

  2. Purchase or Obtain a Certificate
    Select a trusted CA (e.g., Let's Encrypt, DigiCert) and complete the verification process.

  3. Install the Certificate on Your Server
    Follow your server's documentation (e.g., Apache, Nginx) to deploy the certificate.
