----------------------------------
Summary: Hadoop crypto codec framework and crypto codec
implementations
Key: HADOOP-9331
URL: https://issues.apache.org/jira/browse/HADOOP-9331
Project: Hadoop Common
Issue Type: New Feature
Affects Versions: 3.0.0
Reporter: Jerry Chen
For use cases that deal with sensitive data, we often need to encrypt data to
be stored safely at rest. Hadoop common provides a codec framework for
compression algorithms. We start here. However because encryption algorithms
require some additional configuration and methods for key management, we
introduce a crypto codec framework that builds on the compression codec
framework. It cleanly distinguishes crypto algorithms from compression
algorithms, but shares common interfaces between them where possible, and also
carries extended interfaces where necessary to satisfy those needs. We also
introduce a generic Key type, and supporting utility methods and classes, as a
necessary abstraction for dealing with both Java crypto keys and PGP keys.
The task for this feature breaks into two parts:
1. The crypto codec framework that based on compression codec which can be
shared by all crypto codec implementations.
2. The codec implementations such as AES, RC4 and others.
