public interface DeterministicAeads
extends DeterministicAead

Interface for Deterministic Authenticated Encryption with multiple Associated Datas

This interface is a generalization of DeterministicAead: DeterministicAead requires exactly one associated data, while DeterministicAeads allows a list of associated datas. If the list has size 1, the behavior must be exactly the same the methods of DeterministicAead.

For why this interface is desirable and some of its use cases, see for example RFC 5297 section 1.3.

Warning

Unlike Aead, implementations of this interface are not semantically secure, because encrypting the same plaintext always yields the same ciphertext.

Method Summary

Modifier and Type	Method	Description
byte[]	decryptDeterministicallyWithAssociatedDatas(byte[] ciphertext, byte[]... associatedDatas)	Deterministically decrypts ciphertext with a list of associated authenticated data.
byte[]	encryptDeterministicallyWithAssociatedDatas(byte[] plaintext, byte[]... associatedDatas)	Deterministically encrypts plaintext with a list of associated authenticated data.
