* If you wish to add test cases, the following must be done:
* 1. Add a @run line with the parameter being a name for the test case
* 2. Create the ClientHello as a byte[]. It should be a complete TLS
* record, but does not need upper layer headers like TCP, IP, Ethernet, etc.
* 3. Create a new TestCase instance, see "noPskNoKexModes" as an example
* 4. Create a mapping between the test case name in your @run line and the
* TestCase object you created in step #3. Add this to TESTMAP.

// Canned client hello messages
// These were created from packet captures using openssl 1.1.1's
// s_client utility. The captured TLS record containing the client
// hello was then manually edited to remove or add fields if the s_client
// utility could not be used to generate a message with the desired

// be taken to change the lengths of the extensions themselves, the
// extensions vector length, the handshake message length, and the TLS
// record length.

// both absent. Required manual removal of the psk_key_exchange_modes
// extension. Similarly formed Client Hello messages may be generated
