Verify an Agent Receipts chain

Paste or load a receipt or chain and verify it here. The cryptographic checks run in WebAssembly compiled from the same Go verify core as the obsigna receipt verify CLI — there is no separate browser reimplementation, so what you run here matches what an auditor runs on the command line.

Issuer public key PEM-encoded Ed25519 (SPKI). Verification proves consistency under this key; you must obtain and trust the key out of band. Receipt JSON

External anchor proof (optional)

An anchor proof corroborates the chain head out of band and is what separates a full pass from a qualified one. Paste a signed checkpoint and the anchor public key it was signed with: when the checkpoint verifies and commits to this chain's head, the verdict rises to full. The anchor key is obtained and trusted separately from the issuer key.

Anchor public key PEM-encoded Ed25519 (SPKI) — the key the checkpoint was signed with. Signed checkpoint
