Hybrid Cryptography Framework
Hybrid KEMs, multi-algorithm CMS, and X.509 compatibility for staged migration.
Hybrid KEM Support
X25519+ML-KEM-768 for TLS 1.3 with backward-compatible fallback options
Multi-Algorithm CMS
Enveloped data with multiple recipient profiles supporting classical and PQC algorithms
X.509 Compatibility
Dual-signature certificates and hybrid certificate chains for gradual rollout
Migration Strategies
Proven deployment patterns for transitioning existing infrastructure to quantum-safe crypto
Migration Approach
Assess Current State
Inventory classical algorithms, identify high-value targets, map dependencies
Deploy Hybrid Algorithms
Add PQC alongside classical crypto without breaking existing clients
Gradual Client Migration
Roll out PQC support to clients incrementally with feature flags and monitoring
Pure PQC Mode
Transition to PQC-only once all clients support quantum-safe algorithms
Risk Mitigation: Maintain backward compatibility while gaining quantum resistance
