Expected log hash

3bc66074c7b0a853326bf5ba0590a111eee6455dac5c98c791c22eeea9a48920 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 (ffbc979c8901…), 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.
