 *
 * TLS key schedule tests
 *
 * TLS version 1.3 example handshake traces are provided in RFC 8448.
 * We include the "Simple 1-RTT Handshake" and "Resumed 0-RTT
 * Handshake" test cases, to exercise all successful code paths for
 * the HKDF-based key schedule (including session resumption).
 *
 * For TLS version 1.2 and earlier, there are no good reference
 * example handshake traces available.  We choose to run through a
 * non-functional minimal handshake that allows us to exercise the
 * relevant code paths and so at least prevent regressions.
