It exists because high-stakes documents — closings, claims, government records — are trusted on faith. H33-Vault makes each one independently re-verifiable without exposing its contents.

The sensitive fields inside those documents — SSNs, bank accounts, medical records — sit in plaintext databases, protected by nothing more than access controls and audit logs. When a breach happens, the data is already in the clear.
We built H33-Vault to fix this — without touching your database, without changing your workflow, without a migration.
See How It WorksH33-Vault is a joint product from H33.ai and Cachee.ai that brings real cryptography to document validation pipelines.
Not checkbox compliance. Cryptographic proof.
H33 Products · High-Stakes Document Validation
H33-Vault is a high-stakes document-validation product. It validates the documents that decisions and money ride on — mortgage closings, insurance claims, government records — proving each field is genuine, unaltered, and compliant without exposing the sensitive values inside. It owns the document-validation workflow, the operator review experience, and the tamper-evident outcome. It does not own, redefine, or reimplement the encryption, proof, verification, signing-key custody, or governance it relies on; it composes them.
The product boundary. H33-Vault owns the document-validation workflow and outcome. It uses H33 mechanisms for privacy, evidence, verification, signing-key custody, and governance; it does not redefine or own those mechanisms.
Fully homomorphic encryption (BFV) lets Vault validate encrypted fields — range checks, deadline checks — without ever decrypting them. Vault consumes FHE; it does not define or implement it.
Verification is what turns the SHA3-256 proof chain into a reproducible pass/fail verdict anyone can re-check offline. Vault requests and surfaces that verdict; the verifying is owned elsewhere.
H33-74 supplies the portable post-quantum attestation behind the self-contained verification receipt each validated document carries. Vault attaches receipts; it does not produce the attestation primitive.
H33-Key owns custody of the Dilithium signing keys used to sign each validation event. Vault consumes that custody; it does not own or manage the signing keys itself.
Agent-008 governs any automated decisioning that acts on a Vault verdict — preserving authority and preventing drift. Vault is governed by it; it does not perform governance.
If Vault swapped BFV for another confidential-computing technology, or Dilithium for another post-quantum signature, it would still be H33-Vault: the document-validation workflow and tamper-evident outcome are the product. Mechanisms are chosen, not owned.
Cachee.ai provides the speed infrastructure underneath H33-Vault. Field retrieval under 15 milliseconds. L1 in-process DashMap overlay with a 5-second TTL, backed by a Redis-protocol L2 layer. 99.9% cache hit rate at steady state.
For a 500-person operations floor processing mortgage documents, that sub-15ms retrieval eliminates the 15-second field load times that plague legacy systems. At 8 hours per operator per day, that is 125 hours per day returned to productive work.
The entire cryptographic pipeline — commitment, proof, verification, velocity counter increment — completes before the operator’s finger lifts off the mouse button.

No RSA. No ECDSA. No plaintext audit logs pretending to be security.
Pure H33 stack: BFV FHE + SHA3-256 proofs + Dilithium signatures + Cachee speed.
H33-Vault seals your documents. H33-Share lets banks do what they’ve always wished they could — share fraud intelligence across institutions — without violating a single regulation. Each bank defines its own data parameters and categories. Nothing leaves your perimeter unencrypted. Fully customizable. Legal. Private. Instant.

1.3ms, including FHE field encryption, SHA3-256 proof generation, and Dilithium signing. Vault-0 (Dilithium + SHA3 only) is faster since it skips FHE. Vault-3 adds TEE and biometric steps but stays under 5ms for most documents.POST /v1/vault/validate request with your document payload and tier selection. The response includes encrypted field commitments, the Dilithium signature, and a verification receipt. SDKs are available for Python, Node.js, Go, and Rust. Most integrations take under an hour.h33-verify CLI tool or any Dilithium-compatible library. No network call to H33 is required for re-verification.h33-verify CLI tool performs offline verification against the embedded proofs without contacting any server. This is critical for air-gapped environments and legal proceedings where network access isn't available.POST /v1/vault/validate-batch endpoint accepts up to 100 documents per request. Batch processing shares a single Dilithium signing context across the set, which reduces per-document overhead. A 100-document batch at Vault-1 typically completes in under 80ms total.Use H33-Vault when the problem is validating a high-stakes document — mortgage closings, insurance claims, government records — where you need to prove each field is genuine, unaltered, and compliant without exposing the sensitive values. The FHE field validation, SHA3-256 proof chain, Dilithium signing, and offline verification receipt are live; SOC 2 is in progress and HIPAA technical-safeguard support is available for enterprise accounts. Any latency or throughput figures shown are illustrative — verify current numbers on /benchmarks/.
When NOT to use it — use a neighbor instead. If you need to prove upstream systems actually recorded what they claim happened, use H33-Upstream instead. If you need to secure the API keys and secrets your services use, use H33-Gateway instead. To prove the binaries running on your servers are the approved ones, use Sentinel instead.
If you want the mechanism, not the product. For the privacy mechanism itself, read FHE. For the proof/verdict layer, read Verification. For the portable attestation primitive, read H33-74. For signing-key custody, read H33-Key.
