TLS & PKI Certificate Management — The Certificate Lifecycle

A hands-on mid-level course that runs certificates and trust without outages or weak crypto. Climb the certificate lifecycle - eight steps: Plan, Generate, Issue, Deploy, Validate, Monitor, Renew, and Revoke - building a CA hierarchy, strong TLS, automated renewal, and revocation with real OpenSSL and ACME work. Strictly defensive. Four hands-on activities in every lesson.

What you'll learn

• Design a CA hierarchy and generate keys and CSRs correctly.
• Issue and deploy certificates with strong TLS configuration.
• Validate chains, monitor expiry, and automate renewal with ACME.
• Revoke compromised certificates and manage trust stores.
