----------------------------------
[[email protected]] take a look at my slides -

>From a user point of view, they need to configure a KeyProvider such as Hadoop
>or Ranger KMS and specify the table properties controlling which columns to
>encrypt. Decryption happens automatically, if you have access to the key.
> Add column level encryption to ORC files

> It would be useful to support column level encryption in ORC files. Since
> each column and its associated index is stored separately, encrypting a
> column separately isn't difficult. In terms of key distribution, it would
> make sense to use an external server like the one in HADOOP-9331.
