01
Encrypt locally
AES-256-GCM in your browser. Plaintext stays on your device.
How it works
Encrypt. Seal. Release.
Three visible steps. Your keys never leave your device.
02
Seal a capsule
A tamper-evident package with a signed provenance receipt.
03
Release to a buyer
Re-encrypt the key to the buyer. They decrypt locally.
Honest provenance
Proof of origin. Not truth.
A receipt proves who sealed a capsule and when. It never claims the content is accurate.
What it proves
An authenticated LoopXXI session sealed this exact capsule at a specific time. The receipt is tamper-evident and publicly verifiable.
- Identitysigned
- Timestamprecorded
- Integrityverifiable
What it does not prove
The receipt does not certify that the capsule is true, complete, accurate, or valuable. Buyers still judge the content.
- Truthnot claimed
- Accuracynot claimed
- Trustbuyer decides
Founding pilot
