One cryptographic foundation. Multiple products. Verifiable authority.
Post-Quantum Security. Without the Traditional Weight.
H33 is designed to make post-quantum security lighter, more efficient, and more economical to operate — while giving organizations independently verifiable evidence of critical actions and decisions.
Stronger protection · Less overhead · More accountability
AI Governance · AI Audit Trails · Independent Verification · RWA Tokenization · Asset Provenance · Chain Portability · Post-Quantum Security
H33 combines authority preservation, post-quantum cryptography, and independent verification through APIs, SDKs, and terminal tooling. H33-74 creates a portable 32-byte verification footprint while data remains exactly where it is, enabling third parties to independently verify decisions, approvals, and actions without relying on H33 or the original system.
"H33 does not make agents smarter. H33 makes them stop relying on memory."
One H33. Every capability.
Nothing to install. Discover, access, and operate everything available to you through one unified interface — H33 handles identity, authorization, product discovery, and governance behind the scenes.
Authority and proof that survive change.
Systems evolve. Models change. Vendors disappear. H33 binds authority and evidence cryptographically so decisions can remain independently verifiable beyond the systems that produced them.
Govern the action
Establish and enforce cryptographic authority before a consequential action occurs — who may act, over what, under which conditions, and for how long.
Prove the outcome
Preserve independently verifiable evidence of what actually happened — evidence that stays useful after the model, the vendor, or the infrastructure has changed.
AI Safety and Cryptographic Authority Are Different Problems.
AI safety focuses on model behavior, outputs, and safeguards. H33 addresses the cryptographic authority and accountability of actions taken by AI agents, humans, and enterprise systems.
H33 establishes whether actions were authorized, preserves evidence of what occurred, and enables independent verification and replay.
| AI Safety asks | H33 asks |
|---|---|
| Is the model behaving safely? | Was the action authorized? |
| Is the output appropriate? | Can the action be independently verified? |
| Did the model follow its instructions? | Was authority cryptographically enforced? |
| Can behavior be monitored? | Can evidence be independently verified and replayed? |
These layers are complementary, not competing. H33 does not replace model safety systems, and behavioral safety platforms can also offer authorization controls. What H33 adds is a cryptographic layer: authority that is enforced, and evidence a third party can check without trusting the model, the vendor, or H33.
One Platform for Post-Quantum Cybersecurity, AI Governance, and Cryptographic Verification.
H33 combines post-quantum cryptography, AI agent governance, fully homomorphic encryption (FHE), zero-knowledge proofs (ZK), cryptographic authority, and independent verification in one cybersecurity platform.
These capabilities work together to authorize and govern AI agents, protect credentials, secure enterprise APIs, perform computation on encrypted data, and produce independently verifiable evidence of critical actions.
The result is one underlying architecture supporting purpose-built solutions for AI security, post-quantum migration, financial infrastructure, software integrity, and enterprise cybersecurity.
This diagram is conceptual. It shows shared cryptographic lineage, not a claim that every product uses an identical execution path or the same dependencies. The architecture documentation describes what each product actually invokes.
Post-Quantum Protection Without Post-Quantum Bloat.
Making Post-Quantum Security Lighter, Not Heavier.
H33-74 binds an operation to its underlying cryptographic evidence with a compact 74-byte attestation — so systems exchange or anchor that artifact without repeatedly carrying the full evidence package, reducing duplicated evidence movement, storage overhead, and verification friction while preserving independent accountability.
74 bytes is the engineering. Lower overhead at scale is the business opportunity.
Why the overhead is real — measured, not asserted
On identical Graviton4 hardware, one ML-DSA-65 signature is 3,309 bytes against 64 bytes for classical Ed25519 — a 52× increase in signature size, the post-quantum weight every organization inherits per signed event. In the same measurement, ML-DSA-65 verification is faster than Ed25519 (24µs vs 52µs).
Signature and key sizes, latencies, batch throughput and test conditions: ML-DSA-65 benchmark report📐 Sizes, latencies, conditions →.
Compact
A 74-byte structure: a 32-byte commitment plus a 42-byte companion carrying lineage and version metadata.
Portable
Designed to move across systems, networks, and infrastructure — APIs, storage, devices, and ledgers.
Verifiable
Supports independent verification🔎 Verify offline with the open Verifier CLI → using the associated evidence and verification material.
The 74 bytes is the portable artifact; the underlying evidence and the three NIST post-quantum signatures (ML-DSA, FALCON, SLH-DSA) travel alongside it, not inside it — so a 74-byte attestation does not imply a 74-byte total cost. Full size & evidence breakdown →

Define Authority. Enforce Accountability.
H33 provides post-quantum cryptographic governance for autonomous agents, enterprise systems, and sensitive workflows.
H33-Key — AI Credential Security and Secret-Use Control. A new category, distinct from password managers (storage) and vaults (management). H33-Key lets agents and humans use secrets — API keys, tokens, signing material — without ever exposing them to the terminal, clipboard, logs, screenshots, or AI vision.
Post-Quantum, End-to-End — From NIST Level 1 to Level 5
Don't build post-quantum primitives yourself. H33 exposes the full PQ, FHE, and ZK stack through one authenticated interface. Same primitives. Same audit posture. Production-ready.
Level 1 ~128-bit · Level 3 ~192-bit (H33 default) · Level 5 ~256-bit — ML-DSA, SLH-DSA, FALCON.

Walk through all five subsystems →From Encrypted AI Processing to Cryptographic Verification
Every AI and enterprise decision becomes cryptographically verifiable audit evidence.
H33 continuously generates cryptographically verifiable audit trails for AI systems, enterprise infrastructure, financial systems, and sensitive operational environments — capturing what executed, what governance rules were active, what runtime produced the result, and whether the outcome can be independently verified later.
H33 combines cryptographic authorization, policy enforcement, privacy-preserving computation, post-quantum attestation, and independent verification to govern critical AI and enterprise operations. Each workflow uses the capabilities required for its purpose while preserving independent security boundaries.
Protected Computation. Customer-Controlled Release.
H33 does not decrypt protected customer data inside H33-operated compute wherever the requested consequence can be performed on protected data. Across supported FHE, biometric, AI/model-input, financial-computation, lookup, tool, cache, and intermediary workflows, computation occurs on protected data, producing a protected or authorized result.
When plaintext release is necessary, the customer explicitly establishes and controls the key and release boundary — preserving the distinction between protected computation and authorized plaintext release.
No unnecessary decryption. No surrendering control of customer data to obtain useful computation.

Verification Should Survive Change.
Most systems are portable. Their evidence is not.
H33-74 was designed to survive changes in infrastructure. Organizations replace:
Evidence should not have to start over every time infrastructure changes. H33-74 preserves verification continuity across those transitions.

Quantum Migration Is Not Optional
Classical public-key systems are on a migration clock. H33 is built for the systems that have to survive that transition — including blockchain migration, where evidence must survive a change of chain.
The bigger risk isn't just broken encryption. It's unverifiable operations. AI systems, digital asset platforms, insurers, and enterprises are rapidly losing the ability to independently prove how decisions were made and whether controls actually executed.
The next migration challenge is blockchain migration. Organizations increasingly need cryptographic evidence that survives changes in chains, vendors, models, personnel, and infrastructure. See Continuity Portability →
Harvest Now, Decrypt Later
Nation-states capture encrypted traffic today. When quantum computers arrive, they decrypt everything retroactively.
