Five proprietary cryptographic engines. BFV exact arithmetic, CKKS approximate arithmetic, Dilithium post-quantum signatures, ZK-STARK proofs, and FHE-IQ automatic routing. All in a single REST API call. No GPU. No cryptography PhD.
The H33 FHE Platform is the system that runs computation directly over ciphertext — it never decrypts the data to compute on it. That is the single verb it owns: it computes on encrypted data. Everything on this page — the five engines, the API, FHE-IQ routing — is a supporting expression of that capability. This platform page is part of the FHE Platform neighborhood, which computes on encrypted data.
Why it exists: traditional encryption forces you to decrypt before you can use data, and that decryption window is the exposure. FHE removes the window — the server processes ciphertext and returns an encrypted result only the key holder can open. Performance figures on this page are measured benchmarks; see Benchmarks for the underlying runs.
Fully homomorphic encryption has been a theoretical breakthrough trapped in academic labs. Existing implementations are too slow, too complex, and too hardware-dependent for production workloads. That changes today.

H33 is the only FHE platform that combines five cryptographic engines into a single API designed for production workloads (see measured benchmarks). BFV for exact arithmetic, CKKS for approximate arithmetic, FHE-IQ for automatic routing, plus post-quantum signatures and zero-knowledge proofs in every operation.
No rip-and-replace. No new infrastructure. One API call wraps what you already run.
It runs computation directly over ciphertext without ever decrypting the underlying data. You send encrypted inputs, it computes, and it returns an encrypted result that only your key opens.
It does not decrypt your data to compute on it, and it does not prove a statement while revealing nothing — that is zero-knowledge, a separate primitive.
FHE runs computation over encrypted data (ciphertext) without decrypting it; the ZK Platform proves a statement is true without revealing the underlying data. Compute vs. prove.
FHE computes on encrypted data; H33-74 produces the portable, offline-verifiable evidence that a computation happened. Neither owns the other — they are complementary layers.
When you must compute on data that must stay encrypted the whole time — not when you only need to prove a fact without revealing it (choose ZK for that).
Five engines, one API call, 35.25 microseconds. No GPU. No PhD. No excuses left to delay encrypted compute.
