Class AEADEncDataPacket

java.lang.Object

org.bouncycastle.bcpg.Packet

org.bouncycastle.bcpg.InputStreamPacket

org.bouncycastle.bcpg.AEADEncDataPacket

All Implemented Interfaces:

AEADAlgorithmTags, BCPGHeaderObject, PacketTags

public class AEADEncDataPacket
extends InputStreamPacket
implements AEADAlgorithmTags, BCPGHeaderObject

Packet representing non-standard, LibrePGP OCB (AEAD) encrypted data. At the moment this appears to exist in the following expired draft only, but it's appearing despite this. For standardized, interoperable OpenPGP AEAD encrypted data, see SymmetricEncIntegrityPacket of version SymmetricEncIntegrityPacket.VERSION_2.
