Example Handshake Traces for TLS 1.3
draft-thomson-tls-tls13-vectors-01
Examples of TLS 1.3 handshakes are shown. Private keys and inputs are provided so that these handshakes might be reproduced. Intermediate values, including secrets, traffic keys and ivs are shown so that implementations might be checked incrementally against these values.
This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

TLS 1.3 [I-D.ietf-tls-tls13] defines a new key schedule and a number new cryptographic operations. This document includes sample handshakes that show all intermediate values. This allows an implementation to be verified incrementally, examining inputs and outputs of each cryptographic computation independently.
Private keys are included with the traces so that implementations can be checked by importing these values and verifying that the same outputs are produced.
Ephemeral private keys are shown as they are generated in the traces.
The server in most examples uses an RSA certificate with a private key of:

In this example, the simplest possible handshake is completed. The server is authenticated, but the client remains anonymous. After connecting, a few application data octets are exchanged. The server sends a session ticket that permits the use of 0-RTT in any resumed session.
- Note:
- This example doesn’t include the calculation of the exporter secret. Support for that will be added to NSS soon.
