I2NPMessage
public class OutboundTunnelBuildReplyMessage extends TunnelBuildReplyMessage
Sent from the OBEP to the tunnel creator via an inbound tunnel. Contains one plaintext variable-sized reply record for the creator and a variable number of encrypted records for the following hops. This message must be garlic-encrypted to hide the contents from the OBGW. Preliminary, see proposal 157.- Since:
- 0.9.50
