> 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.
