Replace RSA Encryption in Production

Move from RSA/ECC to post-quantum cryptography without downtime, rewrites, or a full infrastructure rebuild.

Start Migration → See API

RSA / ECC → H33 API → PQ encrypted result

Replacing RSA is not just swapping algorithms.

Key exchange changes — TLS handshakes, session establishment
Certificate workflows change — X.509 chains, internal CA
Authentication flows change — JWT signing, API auth
Compliance evidence changes — audit trails, attestation
Legacy clients still need support — backward compatibility
Downtime risk is real — production systems can't go dark

Migrate in stages.

Inventory RSA/ECC usage

Identify every system using asymmetric cryptography. Run HICS scan for automated detection.

Add H33 API in hybrid mode

Route through H33 alongside existing crypto. Both run. No disruption.

Route sensitive workflows through PQ

Start with high-value data: medical, financial, legal, auth tokens.

Add PQ signatures and proofs

ML-DSA signatures replace RSA/ECDSA. ZK-STARK proofs for computation integrity.

Cut over high-risk systems first

Systems with long-term data confidentiality requirements migrate first.

Expand across the stack

Roll out to remaining systems. HATS attests continuous PQ compliance.

Start hybrid. Move fully post-quantum when ready.

H33 lets teams deploy PQC alongside existing systems so migration does not become an all-or-nothing rewrite. Classical and post-quantum algorithms run in parallel. If the PQ layer has an issue, the classical layer catches it. Migrate at your pace.

Step-by-step:

Audit encryption systems
Deploy hybrid PQC alongside RSA
Replace key exchange first
Migrate signatures
Verify compliance with HATS attestation

Replace RSA without breaking production.
