- OCSP responses can indicate good, revoked, or unknown certificate status
- OCSP Stapling improves performance by including responses in SSL handshake
- CRL Overview
- CRL contains revoked certificates before expiration
- Revocation can be irreversible or temporary (hold)
- CRLs are stored at CRL Distribution Points (CDPs)
