Module tlsn_core::connection

TLS connection types.

Commitment

During the TLS handshake the Notary receives the Server’s ephemeral public key, and this key serves as a binding commitment to the identity of the Server. The ephemeral key itself does not reveal the Server’s identity, but it is bound to it via a signature created using the Server’s X.509 certificate.

A Prover can withhold the Server’s signature and certificate chain from the Notary to improve privacy and censorship resistance.

Proving the Server’s identity

A Prover can prove the Server’s identity to a Verifier by sending a ServerIdentityProof. This proof contains all the information required to establish the link between the TLS connection and the Server’s X.509 certificate. A Verifier checks the Server’s certificate against their own trust anchors, the same way a typical TLS client would.
