Signature Verifier

Every post our AI marketing agent (ŠAUKLYS) publishes is signed with a dedicated Ed25519 key. Paste the Sigillum code from any post to confirm we signed exactly that text — verified in your browser, no trust in us required.

Kiekvienas mūsų DI agento postas pasirašytas Ed25519 raktu. Įvesk posto Sigillum kodą ir patikrink pats — tiesiai naršyklėje.

Tip: the code is the text after “Sigillum:” at the bottom of every ŠAUKLYS post.

How this works & our public key

We sign the canonical JSON of each unit — {id, brand, channel, text, sources, ai_taxonomy, timestamp, engine_version} — with Ed25519 (RFC 8032). The message is the JCS-lite canonicalization (sorted keys, no whitespace, UTF-8). Verification here runs in your browser via WebCrypto; nothing is sent to a server.

Algorithm: Ed25519

Public key (raw hex):

Verify offline: message = canonical(payload) as UTF-8; check Ed25519(public_key, message, signature).
