Advanced SSL configurations can significantly improve performance and security. Understanding optimization techniques helps you maximize SSL benefits while minimizing overhead.
Advanced SSL optimization techniques
1. OCSP stapling
OCSP (Online Certificate Status Protocol) stapling includes certificate validation in the SSL handshake, eliminating separate OCSP requests that add latency.
Benefits:
- Faster handshakes
- Reduced server load
- Better privacy (no external OCSP queries)
2. Perfect Forward Secrecy (PFS)
PFS ensures that even if private keys are compromised, past sessions remain secure. Uses ephemeral key exchange (DHE/ECDHE).
Benefits:
- Enhanced security
- Protection against key compromise
- Industry best practice
3. HTTP/2 and HTTP/3
Modern HTTP versions reduce SSL overhead through:
- Multiplexing – Multiple requests over one connection
- Header compression – Reduces data transfer
- Server push – Proactive resource delivery
4. Session resumption
Reuses encryption keys from previous sessions, eliminating handshake overhead for returning visitors.
5. Cipher suite optimization
Prioritize modern, fast ciphers:
- ECDHE-RSA-AES256-GCM-SHA384
- ECDHE-RSA-AES128-GCM-SHA256
- Avoid weak ciphers (RC4, MD5)
Performance benchmarks
Advanced SSL optimizations can achieve:
- Handshake time – Under 100ms with OCSP stapling
- Overhead – Less than 1% with HTTP/2
- Throughput – Near-HTTP speeds with modern ciphers
Implementation steps
- Enable HTTP/2 – Configure server for HTTP/2 support
- Configure OCSP stapling – Set up stapling in server config
- Optimize cipher suites – Prioritize modern ciphers
- Enable PFS – Use ECDHE/DHE key exchange
- Test configuration – Use SSL Labs for grading
