SSL Certificates

A SSL certificate is a digital certificate that authenticates the identity of a website and enables an encrypted connection using the TLS protocol.

Key Concepts

  • Purpose: Ensures secure communication between a client and a server by encrypting data.
  • Types:
    • Domain Validated (DV) certificates
    • Organization Validated (OV) certificates
    • Extended Validation (EV) certificates
  • Issuers: Certificate Authorities (CAs) like Let’s Encrypt, DigiCert, and GlobalSign.
  • Expiration: Certificates have a validity period, typically 1-2 years.

Implementation

  • Generation: Using tools like OpenSSL or automated services like Let’s Encrypt.
  • Deployment: Installed on web servers (e.g., Apache, Nginx) or Cloudflare.
  • Renewal: Automated renewal is recommended to avoid expiration.
  • Public Key Infrastructure (PKI)
  • HTTPS
  • TLS Handshake
