New creates a new Noise transport using the given private key as its libp2p identity key.

ID is the protocol ID for cert.

LengthPrefixLength is the length of the length prefix itself, which precedes all transport messages in order to delimit them.

MaxPlaintextLength is the maximum payload size.

MaxTransportMsgLength is the Noise-imposed maximum transport message length, inclusive of the MAC size (16 bytes, Poly1305 for noise-libp2p).

Transport implements the interface sec.SecureTransport https://godoc.org/github.com/libp2p/go-libp2p-core/sec#SecureConn.
