From AEADMode

authenticated bool authenticated(): Undocumented in source. Be warned that the author may not have intended to support it.
setAssociatedData void setAssociatedData(const(ubyte)* ad, size_t ad_len): Set associated data that is not included in the ciphertext but that should be authenticated. Must be called after setKey and before finish.
setAssociatedDataVec void setAssociatedDataVec(Vector!(ubyte, Alloc) ad): Undocumented in source. Be warned that the author may not have intended to support it.
defaultNonceLength size_t defaultNonceLength(): Default AEAD nonce size (a commonly supported value among AEAD modes, and large enough that random collisions are unlikely).
tagSize size_t tagSize(): Return the size of the authentication tag used (in bytes)
