Radius PEAP protocol

[Juan Daniel Moreno]

Hi everyone, 

I am trying to create a client's interface for Radius PEAP protocol.
The server has donne all I wonder it to do, but now I have a question
about the finish handshake message I have to send. When I get the
server's cetificate, I get a public key too. I have to
"public-key-encrypt" a PreMasterSecret that is a vector of 46 random
bytes and the tls version (1.0).

My question is how can I do that. Am I obliged to get the ssl
libraries to "public-key-encrypt" this packet? Thank you for any
complemetary information.
