> Key: PARQUET-1373
> URL: https://issues.apache.org/jira/browse/PARQUET-1373
> Project: Parquet
> Issue Type: New Feature
> Components: parquet-mr
> Reporter: Gidon Gershinsky
> Assignee: Gidon Gershinsky
> Priority: Major
>
> Parquet Modular Encryption
> ([PARQUET-1178|https://issues.apache.org/jira/browse/PARQUET-1178]) provides
> an API that accepts keys, arbitrary key metadata and key retrieval callbacks
> - which allows to implement basically any key management policy on top of it.
> This Jira will add tools that implement a set of best practice elements for
> key management. This is not an end-to-end key management, but rather a set of
> components that might simplify design and development of an end-to-end
> solution.
> This tool set is one of many possible. There is no goal to create a single or
> “standard” toolkit for Parquet encryption keys. Parquet has a Crypto Factory
> interface [(PARQUET-1817|https://issues.apache.org/jira/browse/PARQUET-1817])
> that allows to plug in different implementations of encryption key management.
