I am not sure what your intention is. In case you are looking for a 
counterpart to test a server implementation, you can have a look at 
https://gitlab.com/guballa/tlsmate. With that tool you can create and 
execute arbitrary TLS handshake scenarios against TLS servers. The 
TLS-flags extension is not supported (yet), but setting up (or checking) 
any extension as a bytestring is possible. Basic python knowledge is 
required, though.

Thanks,
Jens
