Public verification

Verify a Veridanth authorship proof.

Drop in a veridanth-authorship-*.json file you were given. We'll recompute the HMAC signature and show whether the proof is genuine — without needing a Veridanth account.

What this checks

  • HMAC-SHA256 signature over the manifest using Veridanth's server secret.
  • Document metadata: ownership, word and keystroke counts, paste fraction.
  • Revision-snapshot hashes and writing-session breakdown.
  • When the proof was signed.

The proof file does not include the raw document text — only hashes and counts. The student can share it without revealing the manuscript itself.
