Encryption Key Life Cycle & PKI Explained | Security Best Practices

Encryption plays a critical role in securing digital communications, and understanding the Encryption Key Life Cycle and Public Key Infrastructure (PKI) is essential for cybersecurity. In this video, we dive deep into how encryption keys work, how they are managed, and how certificates are issued, validated, and revoked. What You'll Learn: ✅ Encryption Key Life Cycle – Creation, distribution, rotation, and expiration ✅ Public Key Infrastructure (PKI) – The foundation of digital trust ✅ Certificate Authorities (CAs) – The role of Root CA & Intermediate CA ✅ Certificate Signing Request (CSR) – How certificates are generated ✅ Common Name & Certificate Attributes – Identifying secure connections ✅ Certificate Expiration & Renewal – Why certificates expire and what happens next ✅ Certificate Revocation List (CRL) & Online Certificate Status Protocol (OCSP) – Managing revoked certificates
