What CTOs Get From Qryptonic
Technical advisory designed for technology leaders who need to migrate complex systems without disruption.
Architecture Impact Analysis
Understand exactly how PQC algorithms affect your system performance, key sizes, bandwidth, and storage. No surprises during migration.
Migration Planning
Phased migration roadmaps with clear milestones, rollback strategies, and hybrid cryptography approaches that minimize disruption.
Team Enablement
Technical training for your engineering teams on PQC implementation, algorithm selection, and performance optimization.
Cloud & HSM Integration
Detailed guides for AWS, Azure, GCP, and major HSM vendors. We know the APIs, limitations, and best practices.
Technical Reality Check
PQC isn't a drop-in replacement. Here's what you need to know.
Performance Impact
- →ML-KEM (Kyber) key generation: ~10µs
- →ML-DSA (Dilithium) signatures: ~100µs
- →Key sizes: 800-1500 bytes (vs 32 bytes ECC)
- →Bandwidth impact: 2-5x increase for TLS handshakes
Algorithm Selection
- →ML-KEM-768: Balanced security/performance for key exchange
- →ML-DSA-65: Recommended for most signature use cases
- →SLH-DSA: Stateless, conservative choice for high-security
- →Hybrid modes: Combine classical + PQC during transition
Integration Points
- →TLS 1.3 with hybrid key exchange
- →Certificate chain updates (larger certs)
- →API signature verification timing
- →HSM firmware requirements
