What is Harvest Now, Decrypt Later (HNDL)?

HNDL is an attack strategy where adversaries capture encrypted data today to decrypt later when quantum computers become capable of breaking current encryption. Nation-state actors are already harvesting sensitive data. Qryptonic's Active Verification calculates your cryptographic debt based on data sensitivity, retention requirements, and adversary capability timelines from sources like the Global Risk Institute.

What is post-quantum cryptography (PQC)?

Post-quantum cryptography refers to cryptographic algorithms that are secure against attacks by quantum computers. NIST standardized three PQC algorithms in 2024: ML-KEM (FIPS 203) for key encapsulation, ML-DSA (FIPS 204) for digital signatures, and SLH-DSA (FIPS 205) for hash-based signatures. Qryptonic helps organizations migrate from quantum-vulnerable RSA and ECC to these NIST-approved algorithms.

What is Active Verification and how much does it cost?

Active Verification is a 60+-module quantum cryptographic risk assessment delivered in 7 days. It includes 15 quantum-specific modules for cryptographic debt scoring, PQC readiness analysis, and cryptographic inventory. Time to first findings is 72 hours. The assessment generates audit-ready documentation for PCI-DSS 4.0, HIPAA, SOC 2, NIST CSF, and ISO 27001.

What is the $2M Qstrike26 Challenge?

The Qstrike26 Challenge is a confidence stake backed by commercial underwriting: if Qstrike26 finds zero critical or high-severity cryptographic vulnerabilities during a qualifying 4-month engagement, the client receives $2,000,000. Over 50 engagements have been completed since October 2024 with an . $0 has been paid out. The program has a $4M annual cap.

Does Qryptonic test on real quantum hardware?

Yes. Qstrike26 tests cryptographic implementations against real quantum hardware across 6 gate-based platforms including IBM Quantum, AWS Braket (IonQ, Rigetti), and Azure Quantum. This is real quantum hardware—it's adversary-realistic testing using the same hardware nation-states use to develop quantum attacks.

Is Qryptonic compliant with federal requirements?

Yes. Qryptonic is SAM.gov registered (UEI: FRYFAD3GW5W5, CAGE: 14E99) and compliant with NSM-10 and EO 14028, CISA PQC guidance, NIST 800-171, and CNSA 2.0. We provide CMMC preparation services for defense contractors. Our assessments generate documentation that satisfies federal quantum readiness audits.

When will quantum computers break current encryption?

According to the Global Risk Institute (2024 survey of 32 quantum computing experts), there is a 5-14% probability of cryptographically-relevant quantum computers (CRQC) by 2029 and 20-30% by 2034. However, the HNDL threat is already active—nation-state actors are harvesting encrypted data today. NSA CNSA 2.0 deprecates RSA/ECDSA by 2030 and disallows by 2035, driving urgent migration timelines.

What is the difference between ML-KEM, ML-DSA, and SLH-DSA?

ML-KEM (FIPS 203, formerly Kyber) is for key encapsulation—replacing RSA and ECDH key exchange. ML-DSA (FIPS 204, formerly Dilithium) is for digital signatures—replacing RSA and ECDSA signing. SLH-DSA (FIPS 205, formerly SPHINCS+) is an alternative signature algorithm using hash functions instead of lattice math. All three were standardized by NIST in August 2024.

How does Qryptonic compare to Big 4 consulting for quantum assessments?

Active Verification delivers in 7 days what Big 4 firms quote over 4-8 weeks. Key differentiators: (1) Real quantum hardware testing (Big 4 cannot offer this), (2) 72-hour time to first findings vs 2-3 weeks, (3) 60+ modules vs 10-20, (4) $2M Challenge vs no performance stakes, (5) Vendor-neutral recommendations vs product-driven advice.

How long does PQC migration take for enterprise organizations?

Based on documented deployments and research: Small enterprises (5-7 years), Medium enterprises (8-12 years), Large enterprises/regulated industries (12-15+ years). Apple took 2+ years to develop PQ3. Cloudflare has been iterating since October 2022. MDPI research documents 20-40% additional staff overhead for hybrid algorithm management. Given CNSA 2.0 deadlines (RSA deprecated 2030, disallowed 2035), organizations should begin planning immediately.

Industry Voices

The Quantum Threat Is Real

Security leaders across government and industry agree: the time to prepare for quantum computing is now.

“We need to be worried about adversaries harvesting encrypted data today with the expectation that quantum computing will allow them to decrypt it in the future. That risk is real, and it is already happening.”

Rob Joyce

Director of Cybersecurity

NSA

“I spent my career in environments where encryption failure means mission failure. Qryptonic applies that standard to enterprise systems.”

Lt. Gen. Mark E. Weatherington, USAF (Ret.)

Chairman

Qryptonic Defense Innovation Council

“Every other tool tells you what's broken today. Active Verification tells you what breaks next, how severe the exposure could be, and where to spend your budget first. That's the difference between a vulnerability list and a migration roadmap.”

Eliot Jung

Vice Chairman for Cybersecurity

Former Executive Director JPMorgan Chase
