// This is a standalone server that uses various bad certificates.
|
|
// The client is expected to connect, initiate an SSL handshake (with SNI
|
|
// to indicate which "server" to connect to), and verify the certificate.
|
|
// If all is good, the client then sends one encrypted byte and receives that
|
|
// same byte back.
|
|
// This server also has the ability to "call back" another process waiting on
|
|
// it. That is, when the server is all set up and ready to receive connections,
|
|
// it will connect to a specified port and issue a simple HTTP request.
