Sealed File Inspector
Drop a .sealed file to verify the issuer signature and inspect the manifest. No upload.
Inspection runs entirely in your browser. The file is parsed locally, the
Ed25519 signature is verified via the WebCrypto API, and nothing leaves
your device unless you explicitly click a registry lookup button below. A
modern browser is required: Safari 17 or later, Chrome 113 or later, or
Firefox 130 or later.

Don't have a sealed file? Try one of these samples: hello-alice.sealed (valid signature, not decryptable), hello-alice-tampered.sealed (signature invalid), tutorial.sealed (classic suite, decryptable with the tutorial identity), tutorial-hybrid.sealed (hybrid post-quantum suite, decryptable with the hybrid tutorial identity), tutorial-hw-p256.sealed (hardware P-256 suite, decryptable with the hardware tutorial identity). Drop any of them into the inspector above.
