# MPC-TLS

During the MPC-TLS phase the `Prover` and the `Verifier` work together to generate an authenticated `Transcript`1 of a TLS session with a `Server`.

Listed below are some key points regarding this process:

- The `Verifier` only ever sees the encrypted application data of the TLS session.
- The protocol guarantees that the `Prover` is not solely capable of constructing requests, nor can they forge responses from the `Server`.
- When the `Verifier` is a `Notary` (see section on Notarization), the identity of the `Server` is hidden and can be proven to another application-specific verifier later.

A transcript is the application level data that is send to and received from the `Server`
