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.
“WARUM werden beim Herunterladen manche Schriftarten kleiner, manchmal verschwinden Elemente und manche Dateien werden unscharf, obwohl das Format PNG oder JPG ist?”

Verify in the public log
- Open the Rekor entry (pre-filled with this proof's log index).
-
In the entry, compare
spec.data.hash.valuewith the "Expected log hash" above: it is the SHA-256 of the Merkle root string (790984da83ec…), which ties this proof's root to the log entry. -
Decode
spec.signature.publicKey.contentfrom base64: it must equal Citatio's published key at /.well-known/citatio-signing.json. -
The entry's
integratedTimeis the independent timestamp: the root, and with it this quote, existed no later than that moment. - 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.
