Hybrid signature schemes for receipts

A hybrid signature scheme signs each receipt with both Falcon-1024 (classical) and ML-DSA (post-quantum), so it stays verifiable if either is broken.

Why Hybrid Signatures?

Verifiable receipts must remain tamper-proof for decades, even as computing power grows. Hybrid signature schemes combine Falcon-1024 (a classical signature algorithm) with ML-DSA-65 or ML-DSA-87 (post-quantum signatures) to protect against both classical and quantum attacks. This dual-layer security ensures your receipts stay verifiable long-term, regardless of future threats.

How Hybrid Signing Works

1. Dual Signing: A document is signed using both Falcon-1024 and ML-DSA (either 65 or 87).
2. Verification: The recipient checks both signatures. If either fails, the receipt is rejected.
3. Long-Term Proof: Even if one algorithm is broken, the other remains valid, preserving the receipt's integrity.
