Class DataCodec

java.lang.Object

org.geysermc.floodgate.core.crypto.DataCodec

Direct Known Subclasses:

AesDataCodec, DataCodecKeyPair

public abstract class DataCodec
extends Object

Responsible for data integrity by either signing or encrypting the data.

Unlike KeyProducer, KeyCodec and Topping this class does have state. For every key a new instance should be made, or use init(Key) to reset that state.

                                 throws Exception

Encodes the given data using the Key provided in init(Key)

Parameters:

plainText - the data to encode

Returns:

the encoded data

Throws:

Exception - when the encoding failed

decode

public abstract ByteBuffer decode(List<ByteBuffer> dataSections)
                           throws Exception

Decodes the given data using the Key provided in init(Key)

Parameters:

dataSections - the data sections to decode

Returns:

the decoded data
