Quote verification

This proves the quote below is recorded by Citatio exactly as displayed and has not been altered since it was committed and anchored. It documents Citatio's crawl observation; it does not imply endorsement by the source platform. The quote links to the original review.

“Service très rapide.”

Checks (re-run on this request)

• ✓ Signature — Ed25519 signature over the record hash, verified against the public key at /.well-known/citatio-signing.json
• ✓ Merkle inclusion — Leaf recomputed through the sibling path to the anchored root
• ✓ Public transparency log — Sigstore Rekor log index 2514654467

Expected log hash

ddd8d6dfa3771a4106292f7bec674337dc9649465b28b118bb17bfc2b8ff0a67 The log entry's spec.data.hash.value must equal this value: the SHA-256 of the Merkle root string above. Recompute it yourself from the root to confirm.

Verify in the public log

1. Open the Rekor entry (pre-filled with this proof's log index).
2. In the entry, compare spec.data.hash.value with the "Expected log hash" above: it is the SHA-256 of the Merkle root string (2030d4ef17fc…), which ties this proof's root to the log entry.
3. Decode spec.signature.publicKey.content from base64: it must equal Citatio's published key at /.well-known/citatio-signing.json.
4. The entry's integratedTime is the independent timestamp: the root, and with it this quote, existed no later than that moment.
5. Locally, without any Citatio infrastructure: SHA-256 the canonical record (must equal the record hash), verify the Ed25519 signature against the public key, and fold the hash through the Merkle path (sorted-pair SHA-256) to reach the anchored root.
