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.
“having masked emails built in, custom aliases, and unlimited(!!) custom domains and catch-all addresses is unlike ANY other email provider that I’m aware of.”
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 2789279696

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 (97eb1062a862…), 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.
