Post-Quantum Encryption API

Replace RSA and ECC with NIST-aligned post-quantum encryption through one API. No rebuild. No infrastructure change. Production-ready today.

encrypt verify prove sign

One request. Four security layers. No plaintext exposure.

Post-quantum migration should not require rebuilding your stack.

RSA and ECC are being phased into a post-quantum transition. Most organizations know they need to migrate, but the hard part is production reality: existing APIs, auth flows, certificates, keys, vendors, and compliance controls are already wired into critical systems.

H33 gives teams a way to add post-quantum encryption without ripping everything apart.

One API replaces the hard parts.

Encryption

Post-quantum encryption for sensitive data and workflows. FHE compute on encrypted data without decryption.

Authentication

Passwordless and biometric-ready authentication. 42µs per auth. Zero plaintext exposure.

Proofs

ZK-STARK proofs for verifiable results. Computation integrity without trusted setup.

Signatures

Post-quantum signatures across three independent families. Durable verification that outlasts the systems it protects.

Aligned with the NIST post-quantum transition.

In simple terms:

Post-quantum migration means replacing RSA and ECC with quantum-safe algorithms like ML-KEM and ML-DSA, without exposing data or breaking systems. H33 handles this through a single API endpoint.

Key takeaway:

You can run post-quantum cryptography in production today without rebuilding your infrastructure.

Run post-quantum today.

Create an API key and test post-quantum encryption without changing your infrastructure.
