Revert a TLS Connection to Plain TCP

See more Socket/SSL/TLS Examples

Demonstrates Socket.ConvertFromSsl, which ends the TLS layer while leaving the underlying TCP connection open for subsequent unencrypted communication.

Background. This is the reverse of a STARTTLS-style upgrade and is valid only while TLS is currently active on the connection.
