net.i2p.data.i2np.InboundTunnelBuildMessage

All Implemented Interfaces:: I2NPMessage

public class InboundTunnelBuildMessage
extends TunnelBuildMessage

Sent from the tunnel creator to the IBGW via an outbound tunnel. Contains one plaintext variable-sized request record for the IBGW and a variable number of encrypted records for the following hops. This message must be garlic-encrypted to hide the contents from the OBEP. Preliminary, see proposal 157.

Since:: 0.9.50
