About this tool and its limits
01 · Problem
The problem
Private chat products ask users to trust a server, organization, and retention system with content they cannot independently inspect.
02 · Change
What changed
Talk derives browser keys, relays ciphertext, and separates authenticated identity from room authorization.
03 · Test
What is being tested
Can a private conversation remain useful while the server stays structurally unable to read it?
04 · Evidence
What can be claimed
- Current scope
- Private encrypted experiment
- Operating cost
- Consequential operation
- Required evidence
- Access live-flow fail-closed probe, no-unsafe-inline CSP assertion, and authenticated proof receipts for Access-cleared shell/assets, stream startup, key exchange, message delivery, decrypt, wrong-key rejection, and proof-channel cleanup.
- Claim limit
- May claim the Access fail-closed boundary and strict-CSP posture from no-secret smoke; may claim authenticated chat, message delivery, and E2EE key-exchange readiness only from a fresh jkca.talk-authenticated-proof/v1 receipt.
