Dear all,
I am working on a EAP/TLS authentication with Freeradius and the Odessey client. After
a client hello message with a bunch of cipher suites, the odyssey client receives a
server hello message with one cipher suites. It responds with a TLS Alert message that
tells the server the cipher suite selection has been fatal!
At the end I attached the complete protocol as well for further studies.
How does Libssl choose the cipher suite?
Kind regards,
Markus
