Expected log hash

1f3acef0f063246e051bf412e40f4279cb96ed334ff7b0647a13320c1b31c4fa 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.

Canonical record

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 (04b39eaa56e1…), 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.
