> Currently BlockCipher interface has methods without letting caller to specify length/offset. In some use cases like Presto,  it is needed to pass in a byte array and the data to be encrypted only occupys partially of the array.  So we need to add a new methods something like below for decrypt. Similar methods might be needed for encrypt. 
> byte[] decrypt(byte[] ciphertext, int cipherTextOffset, int cipherTextLength, byte[] aad);
