  The two are completely independent.

  You don't call the "encryption" functions.  You call "send tls
data", and it takes care of encrypting the data and putting it into a
TLS session.

  Again, see the FreeRADIUS source code for how it handles this.  See
wpa_supplicant (another package) for a client implementation of EAP
that does exactly what you're trying to do.

  I don't understand why it's so difficult to read pre-existing code,
and to use it as examples for new code.
