Subject [jira] [Commented] (HADOOP-9332) Crypto codec implementations for AES
Date Fri, 06 Sep 2013 17:34:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13760393#comment-13760393

Luke Lu commented on HADOOP-9332:

Preliminary comments:
* I had to dig to find out that both SimpleAESCodec and AESCodec are using CTR mode, which
is fine. I was thrown off by the comment in the beginning of the SimpleAESCodec, as we know
AES in the default ECB mode is pretty much worthless. Suggest rename the codec to AESCTRCodec,
unless you're going to support other modes (CBC etc.), which requires an explicit comment.
* There is much code duplication between SimpleAESCodec (without compressor option) and AESCodec
(with compressor option). Suggest consolidate code in one codec.

> This JIRA task provides three crypto codec implementations based on the Hadoop crypto
codec framework. They are:
