Every API key in your database is one breach away from being a weapon.

They sit in plaintext columns, .env files, config repos. AES at rest is meaningless when the app layer holds the decryption key. A single SQL injection, misconfigured S3 bucket, or compromised backup — and every secret in your system is exposed.

H33-Shield uses Kyber-1024 post-quantum encryption and HMAC-SHA3 zero-knowledge verification. Keys are encrypted before they touch any storage. Verification happens without the key ever crossing the network.

Start Protecting

Vault products store encrypted data. Shield protects the keys that unlock everything else — API credentials, database passwords, service tokens, webhook secrets. The keys that, if leaked, give an attacker the same access as your most privileged engineer.

Not another vault. Mathematical invulnerability.

Here’s what happens when you store and verify a secret with H33-Shield.

Step 01 — Kyber-1024 Encryption
Post-Quantum Encryption at Rest
Your secret is encrypted client-side using Kyber-1024 key encapsulation — the NIST-selected post-quantum standard. The plaintext never reaches our servers, logs, or any intermediate cache. Even if someone compromises the entire database, they get Kyber ciphertext that’s computationally infeasible to decrypt without the encapsulated key.

Even if someone compromises the entire database, they get Kyber ciphertext that’s computationally infeasible to decrypt without the encapsulated key.
Step 02 — HMAC-SHA3 Zero-Knowledge Verification
Verify Without Exposing
Need to confirm a key is correct before using it? Shield generates an HMAC-SHA3-256 digest with a unique salt. You send the proof — never the key. The server verifies mathematical equivalence without ever seeing the plaintext. Your API key never traverses the network for verification.

Step 03 — Auto-Rotation + Breach Detection
Rotate Before They Exploit
Set 30, 60, or 90-day rotation policies. Shield generates canary tokens — honeypot credentials planted alongside your real keys. If a canary appears in public repos, paste sites, or dark web dumps, Shield fires a webhook and SES alert within seconds. You know about breaches before attackers can exploit them.

Step 04 — Dilithium-Signed Compliance
Tamper-Proof Audit Trails
Every operation — store, retrieve, verify, rotate, delete — is logged with a Dilithium-3 post-quantum signature. Tamper-proof audit trails that satisfy SOC 2 CC6.1, PCI DSS 10.2, and HIPAA 164.312(b). Generate compliance reports on demand with cryptographic proof of every access.

ZK Verification Pipeline

Every industry has secrets. None of them are safe.

Banking
Protect Stripe keys, payment processor credentials, and interbank auth tokens. Kyber encryption means quantum computers can’t retroactively decrypt harvested data.
Healthcare / HIPAA
EHR API keys, lab integrations, pharmacy system credentials. Dilithium-signed audit trails satisfy HIPAA 164.312(b) access logging requirements.
SaaS / Platform
Secure AWS credentials, Twilio tokens, SendGrid keys, database passwords. Auto-rotation eliminates the “rotate everything” fire drill after a breach.
Government / Defense
NIST PQC Level 1+ encryption for classified system credentials. Threshold access (k-of-n) ensures no single person can access critical secrets.

The more you protect, the less each one costs.
