Digital Certificates | SSL/TLS Certificates, Root Certificates, SAN, Code Signing
Digital certificates are a fundamental part of online security, enabling authentication, encryption, and trust across the internet. In this deep-dive video, we go beyond the basics to explore the various types of certificates, their validation levels, and how they are managed within Public Key Infrastructure (PKI).
What You'll Learn:
✅ Root Certificates & Chain of Trust – How trust is established in PKI
✅ Subject Alternative Name (SAN) – Why it's crucial for multi-domain SSL certificates
✅ Code Signing Certificates – How software authenticity is verified
✅ Self-Signed Certificates – When and why they are used
✅ Email Certificates & User/Computer Certificates – Securing email and device authentication
✅ SSL & TLS Certificates – Understanding validation levels (DV, OV, EV)
✅ Certificate Authorities (CAs) – The role of offline CAs, mesh & bridge models
✅ CRL (Certificate Revocation List) & OCSP – How revoked certificates are managed
✅ OCSP Stapling – Enhancing certificate validation efficiency
✅ Web of Trust – Alternative trust models in cryptography
✅ Key Backup & Recovery – Securing cryptographic keys for business continuity
