Re: [lwip-users] Elevating existing connection to TLS

[Josh McAtee]

Sorry if I wasn't being clear.
Take the existing SMTP app, for example - it uses the altcp layer already.
But, the connection can only be made either with or without TLS from the 
beginning of the connection.
I want to implement STARTTLS, in which the connection starts out plain 
TCP and then is elevated to TLS later, after the STARTTLS command is 
sent from the client (and 220 go ahead received back from the server).
So the TLS handshake starts after the connection has already been 
established and some non-TLS communication has already been made.

Does that make sense?
