Continues a multi-part update of the Additional Authentication Data (AAD), using a subset of the provided buffer.

Calls to this method provide AAD to the cipher when operating in modes such as AEAD (GCM/CCM). If this cipher is operating in either GCM or CCM mode, all AAD must be supplied before beginning operations on the ciphertext (via the update and doFinal methods).

Parameters:

src     the buffer containing the AAD

offset     the offset in src where the AAD input starts

len     the number of AAD bytes

Exceptions:

IllegalStateException if this cipher is in a wrong state (e.g., has not been initialized), does not accept AAD, or if operating in either GCM or CCM mode and one of the update methods has already been called for the active encryption/decryption operation

UnsupportedOperationException if this method has not been overridden by an implementation

Since: 1.7

`src`		the buffer containing the AAD
`offset`		the offset in `src` where the AAD input starts
`len`		the number of AAD bytes

`IllegalStateException`		if this cipher is in a wrong state (e.g., has not been initialized), does not accept AAD, or if operating in either GCM or CCM mode and one of the `update` methods has already been called for the active encryption/decryption operation
`UnsupportedOperationException`		if this method has not been overridden by an implementation
