API v2.0.0
⚛ INTEGRATED POST-QUANTUM REST API v2.0 — DSA + KEM

World's First Integrated
Post-Quantum REST API

Complete PQC Suite: Q-Signer (EC-DSA + ML-DSA-65) & Q-KEM (EC-DH + ML-KEM-768) — Sign AND Encrypt, both quantum-safe.

Integrate ML-DSA-65 (FIPS 204) + EC-DSA hybrid signatures into any application with simple HTTP requests.

ML-DSA-65 (FIPS 204)

NIST post-quantum standard. Signature: 3309 bytes. Security Level 3.

🔐

Hybrid Signature

EC-DSA + ML-DSA-65 simultaneously. Classical + quantum-resistant security.

⚡

Ephemeral Keys

Software TEE method. Private key lifetime under 10 microseconds. Never saved to disk.

ðŸŽē

Hytak TRNG

True Random Number Generator. Patent 1 by Faihoplo Inc.

Real World Demo
Alice (Buyer) & Bob (Seller) — APT Transaction
Complete quantum-safe property purchase using Q-Signer + Q-KEM

🏠 Alice (Buyer) and Bob (Seller) complete a quantum-safe apartment purchase agreement. Using Q-Signer (signing) + Q-KEM (encryption).

Step 1: Bob (Seller) generates ML-KEM-768 key pair

Bob generates ML-KEM-768 quantum-safe keys only. EC-DH is handled internally by the API.

// Bob's keys will appear here...
Step 2: Alice (Buyer) signs purchase agreement

Alice signs the contract with Q-Signer (EC-DSA + ML-DSA-65).

🔐 Signature source: Generated by Hytak TRNG (Patent 1) — Quantum-safe random number generator. Each signature is unique and ephemeral. Private key is immediately zeroized after signing (Patent 2, key lifetime < 10Ξs).

✏ïļ Edit contract message (Alice types her own message):

// Alice's signature will appear here...
Step 3: Alice encrypts signed contract for Bob

Alice encrypts the signed contract using Bob's ML-KEM-768 public key.

// Encrypted contract will appear here...
Step 4: Bob verifies Alice's signature

Bob decrypts and verifies Alice's quantum-safe signature.

// Verification result will appear here...
