Hybrid Cryptographic Implementations – Live Online (Americas), March 2027
The engineering of transition-period cryptography. Covers key exchange, signatures, protocol integration, performance measurement, and exit planning for hybrid (classical + post-quantum) deployments.
Cryptography engineers, protocol implementers, and security architects making hybrid deployment decisions in TLS, SSH, VPN, and code signing. Working familiarity with the protocols is assumed. If you want the design principles rather than the implementation detail, Cryptographic Agility covers the design principles one level up.
What you will cover
- Implement hybrid key exchange in TLS 1.3 using the concatenation and combiner approaches
- Choose between hybrid signature options and defend the choice against the maturity of each
- Size the performance and message-length cost of hybrid deployment on your own protocols
- Sequence a hybrid rollout so classical fallback never silently becomes the permanent state
- Plan the exit: the criteria and steps for retiring the classical half later
The format
