Paired written guide: How to Verify Provably Fair Baccarat Hands (SHA-256 & HMAC)
Key takeaways from this video
- All SHA-256 and HMAC-SHA256 calculations run locally in your browser via the Web Crypto API — zero seeds or session histories are ever uploaded to a server.
- First confirm SHA-256(revealedServerSeed) equals the pre-session commitment hash; that proves the unhashed server seed was locked before your first hand.
- Replay up to 5,000 nonces to inspect every dealt card, natural or third-card draw, and compare the reconstructed 11-column Big Road and derived roads against your session log.

Open baccaratsmart.com/verify to audit any revealed provably-fair server seed, client seed, and hashed commitment. The verifier hashes the revealed server seed with SHA-256 in your browser to confirm it matches the pre-session hash. It then replays up to 5,000 hands via HMAC-SHA256 byte-to-card dealing and applies official third-card tableau rules. Inspect every reconstructed hand and view the verified session as a complete Big Road and derived-road scoreboard.
