public int getOutputSize(int len) Implements org.bouncycastle.crypto.modes.AEADCipher.getOutputSize. Doc from org.bouncycastle.crypto.modes.AEADCipher.getOutputSize. return the size of the output buffer required for a processBytes plus a doFinal with an input of len bytes. The returned size may be dependent on the initialisation of this cipher and may not be accurate once subsequent input data is processed - this method should be invoked immediately prior to a call to final processing of input data and a call to `doFinal(byte[], int)`. Parameters len:int the length of the input. Returns:int the space required to accommodate a call to processBytes and doFinal with len bytes of input.
