Package insecure provides an insecure, unencrypted implementation of the the SecureConn and SecureTransport interfaces.

SecureConn is an authenticated, encrypted connection.

A SecureMuxer is a wrapper around SecureTransport which can select security protocols and open outbound connections with simultaneous open.

A SecureTransport turns inbound and outbound unauthenticated, plain-text, native connections into authenticated, encrypted connections.
