Default AEAD nonce size (a commonly supported value among AEAD modes, and large enough that random collisions are unlikely).
Set associated data that is not included in the ciphertext but that should be authenticated. Must be called after setKey and before finish.
Return the size of the authentication tag used (in bytes)
Returns true iff this mode provides authentication as well as confidentiality.
Interface for AEAD (Authenticated Encryption with Associated Data) modes. These modes provide both encryption and message authentication, and can authenticate additional per-message data which is not included in the ciphertext (for instance a sequence number).
