> Components: parquet-mr
> Reporter: Xinli Shang
> Assignee: Xinli Shang
> Priority: Major
>
> 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);
