H33-74
74 bytes. Any computation. Post-quantum attested. Forever.
32 bytes anchored · 42 bytes portable proof
Post-quantum cryptography and fully homomorphic encryption increase size and complexity. H33-74 keeps the trust layer fixed at 74 bytes for encrypted computation, authentication, and verifiable systems.
Post-quantum cryptography for encrypted computation, authentication, and verifiable data—without exposing plaintext or requiring infrastructure changes.
1.36ms full production auth pipeline · 2,216,488 auth/sec sustained
H33 is a post-quantum cryptography platform combining FHE (fully homomorphic encryption), zero-knowledge proofs, and quantum-resistant authentication into a single API.
Why Fully Homomorphic Encryption Cannot Be Signed — And How H33-74 Solves It
The Problem
- ✕FHE computes on encrypted data
- ✕Signature systems sign plaintext
- ✕Decrypting to sign exposes data
- ✕Signing “inside” FHE is impractical
- ✕Production systems hit a trust boundary
What H33-74 Changes
- ✓Commits to the result without exposing plaintext
- ✓Post-quantum signed (3 independent families)
- ✓Fixed 74-byte persistent footprint
- ✓Chain-agnostic, transport-agnostic
- ✓Independently verifiable
What happens when AI has no cryptographic accountability
Every multi-agent AI pipeline in production operates on trust. That trust has no cryptographic foundation. H33-74 changes that.
The H33-74 Primitive
Every H33 engine exports trust through the same primitive: H33-74.
74 bytes no matter what
Moves through APIs, storage, devices, ledgers
Built for family rotation and long-lived verification
Verification does not depend on trusting H33
Your data never leaves encryption. The computation happens inside it. The result is post-quantum signed at the moment it's produced. The attestation is 74 bytes regardless of size.
Not compression. Commitment.
Same 74 bytes. Six simultaneous roles. All networked.
Post-Quantum Authentication and Encrypted Computation API
One API integrates encrypted computation, proof generation, post-quantum signing, and verification into a single production pipeline.
Compute on protected data
Prove correctness without exposure
Match encrypted identity signals
Attest outputs under PQ signatures
All four export trust through H33-74.
AI Blind processes your data without ever seeing it. H33-74 attests the result without decrypting it.

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.
Harvest Now, Decrypt Later
Nation-states are capturing encrypted traffic today. When quantum computers arrive, they decrypt everything retroactively. Intelligence agencies have confirmed this is happening.
Every Classical Key Is Vulnerable
Shor's algorithm breaks RSA, ECDSA, and Diffie-Hellman. Your TLS certificates, API auth, database encryption, and VPN tunnels. NIST finalized post-quantum standards in 2024.
Data Shelf Life
Cryptographically relevant quantum computers are expected by 2028–2032. Data encrypted today has a 5–7 year shelf life. Federal PQC migration deadline: 2030.
One API. Full Trust Pipeline.
Encrypt → verify → prove → attest
- ✓No infrastructure rebuild
- ✓One request for the full stack
- ✓Independent verification downstream
