Summary: Encryption: Add support for PGP Encryption
Key: MAPREDUCE-4552
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4552
Project: Hadoop Map/Reduce
Issue Type: Sub-task
Components: security
Reporter: Benoy Antony
Assignee: Benoy Antony
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.
