LIVE VERIFIER

Verify a session. In your browser. Right now.

Paste a Sasana session log below, or load a sample. The same checks sasana verify and sasana evidence-pack run on your machine run here — hash chain, sequence, completeness, seal, and the EU AI Act Article 12 evidence checks. Every SHA-256 is computed locally with window.crypto.subtle. Nothing is uploaded.

This is an in-browser port of the Sasana 2.0 verifier: the same checks, statuses and evidence classes as sasana verify, including Ed25519 seal and signature checks (needs a current browser). A seal only proves who sealed a log when you give the verifier the Archeion public key: without it the result is SELF_SEALED_EVIDENCE, because anyone can generate a key and seal a rewritten log. RFC 3161 timestamps are not checked here; use the CLI. See the compliance mapping for what each evidence class shows, or tamper with a log to watch a chain break as you type.
