This is the task of Parquet-1396.
Parquet-1178 introduced the crypto feature to enable encryption for selective columns. However, the upper layer application need to call the new or modified APIs to use it. This could be a problem for existing services that running spark/hive/presto.
Parquet-1396 introduced a non-API way to activate the crypto features by defining an interface and user can implement this interface as a plugin jar.
