POST /v2/pdf/sign — Upload and Sign PDF

Upload any PDF file and sign it with Q-Signer (EC-DSA + ML-DSA-65 FIPS 204).

🔐 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).

Real World Demo
Alice (Buyer) & Bob (Seller) — PDF Contract
Complete quantum-safe property purchase using PQC PDF Signer
Step 1: Alice signs PDF contract with Q-Signer

Alice uploads purchase agreement PDF and signs with quantum-safe signature.

🔐 Signature source: Generated by Hytak TRNG (Patent 1) — Quantum-safe random number generator. Private key zeroized after signing (Patent 2, < 10Ξs).

Upload Alice's PDF contract:

// Alice's signed PDF will appear here...
Step 2: Bob verifies Alice's signature

Bob verifies the quantum-safe signature on Alice's PDF contract.

// Complete Step 1 first, then verify here...
