Package org.tinyradius.packet.util

Class PacketCodec

java.lang.Object
org.tinyradius.packet.util.PacketCodec
public class PacketCodec
extends java.lang.Object
To encode/decode packets to/from Datagram.

A dictionary is required in constructor to avoid passing in dictionary on every conversion - in typical use cases, only one instance of this class will be required as the server/proxy/client will be using one Dictionary.

    • toByteBuf

      public static io.netty.buffer.ByteBuf toByteBuf​(RadiusPacket packet) throws RadiusPacketException
      Throws:
      RadiusPacketException

    • fromDatagramRequest

      public static RadiusRequest fromDatagramRequest​(Dictionary dictionary, io.netty.channel.socket.DatagramPacket datagram) throws RadiusPacketException
      Reads a request from the given input stream and creates an appropriate RadiusPacket/subclass.

      Decodes the encrypted fields and attributes of the packet, and checks authenticator if appropriate.

      Parameters:
      dictionary - dictionary to use for attributes
      datagram - DatagramPacket to read packet from
      Returns:
      new RadiusPacket object
      Throws:
      RadiusPacketException - malformed packet

    • fromDatagramResponse

      public static RadiusResponse fromDatagramResponse​(Dictionary dictionary, io.netty.channel.socket.DatagramPacket datagram) throws RadiusPacketException
      Reads a response from the given input stream and creates an appropriate RadiusPacket/subclass.

      Decodes the encrypted fields and attributes of the packet, and checks authenticator if appropriate.

      Parameters:
      dictionary - dictionary to use for attributes
      datagram - DatagramPacket to read packet from
      Returns:
      new RadiusPacket object
      Throws:
