Verifying the Aviator Game Hash for Fair Play in India

📅 2026-04-16 📂 Indibet Website Blog

This guide shows precise steps to confirm a revealed server seed matches a pre-committed hash and to reproduce round outputs when the operator publishes the algorithm. Follow the commands and checks below to validate fairness yourself.

What to check first: pre-commit and reveal

Illustration of a server-seed precommit and later reveal

Start by locating the operator's fairness page that lists the server-seed hash and explains the RNG formula. Confirm the site reveals the server seed after each round and provides client seed and nonce formats.

  • Confirm published server-seed SHA256 hash exists.
  • Ensure server seed is revealed after the round.
  • Find the exact RNG algorithm on the fairness page.
  • Note client seed and nonce formats used per round.
  • Save published round ID and timestamps for evidence.

Verify the pre-commit

Run a SHA256 on the revealed server seed and compare to the published pre-commit hash.


Step-by-step verification you can run locally

Terminal example showing openssl and Node.js commands

Reproduce the HMAC or hash using the operator's specified inputs and order. Use these commands as templates; substitute the exact seeds and nonce from the round.

  • Compute server SHA256:
    echo -n "REVEALED_SERVER_SEED" | openssl dgst -sha256

  • Compute HMAC-SHA256 (server key):
    printf "%s" "CLIENT_SEED:NONCE" | openssl dgst -sha256 -hmac "REVEALED_SERVER_SEED"

  • Node.js snippet for HMAC:
    const crypto=require('crypto');console.log(crypto.createHmac('sha256',server).update(client+':'+nonce).digest('hex'))

  • Compare produced hex to operator's revealed round value.

  • If algorithm maps hex→multiplier, apply published mapping exactly.

Concrete example (replace placeholders)

Use serverSeed="srv123", clientSeed="user42", nonce=7 as local test; commands above will output hex to compare.


Common mistakes and final checks

Checklist with common verification errors highlighted

Most mismatches come from input order, encoding, or wrong nonce. Fix these first before concluding unfairness.

  • Use exact input order from fairness page.
  • Ensure no extra whitespace or newline in seeds.
  • Match nonce formatting (number or padded string).
  • Confirm hex vs base64 encoding expected.
  • Do not trust screenshots; use raw revealed values.

When operator omits algorithm

If the site does not publish the RNG mapping from hash to multiplier, you can still verify pre-commit integrity but not outcome mapping. Stop and request the algorithm or avoid staking on unverifiable rounds.


Quick Takeaways / FAQ

Quick checklist summary image

Q1: Can I confirm outcome fairness without the algorithm?
A1: You can confirm server-seed pre-commit integrity only.

Q2: Which command reproduces HMAC-SHA256 locally?
A2: Use openssl: printf "CLIENT:NONCE" | openssl dgst -sha256 -hmac "SERVER".

Q3: What common error breaks verification?
A3: Wrong seed order, extra whitespace, or incorrect nonce format.
