[jira] [Commented] (MAPREDUCE-4552) Encryption: Add support for
PGP Encryption
[ https://issues.apache.org/jira/browse/MAPREDUCE-4552?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13568325#comment-13568325 ]
Benoy Antony commented on MAPREDUCE-4552:
-----------------------------------------
Sure. I'll decompose this into smaller patches.
What you mentioned about directory structure is true. If that's going to change, then this feature is going to break. I would need some guidance on this. Once I break it this into smaller patches, we will review that piece separately.

> Provide support for PGP encryption by implementing Encrypter and Decrypter interfaces defined in MAPREDUCE-4450. This can be used by the cluster to protect the job secrets. This also be used map reduce jobs to encrypt/decrypt data.
> Add PGPCodec as a CompressionCodec so that encrypted data can be processed transparently like compressed data . The aliases to the keys can be specified as part of Job.
> Based on PGPCodec, a number of utilities are provided to encrypt, decrypt the data in cluster. They include
> 1. DistributedSplitter – Split an encrypted file into smaller files.
> 2. DistributedEncrypter – encrypt files in a cluster.
> 3. DistributedDecrypter – decrypt encrypted files in a cluster.
> 4. DistributedRecrypter – decrypt an encrypted file and encrypt it with another key.
> Uitlities are added to encrypt/decrypt files in local file system
> 1. Genkey - Generate an asymmetric key pair (public and private keys) of a specified strength
> 2. Encrypt - Encrypt a file
> 3. Decrypt – Decrypt a file
> Added as a contrib project - hadoop-crypto.
