Subject [jira] [Created] (HADOOP-9331) Hadoop crypto codec framework and crypto codec implementations
Date Mon, 25 Feb 2013 03:08:27 GMT
Jerry Chen created HADOOP-9331:

             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.
