Subject [jira] [Commented] (HADOOP-10635) Add a method to CryptoCodec to generate SRNs for IV
Date Thu, 29 May 2014 18:05:03 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10635?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14012634#comment-14012634
] 

Alejandro Abdelnur commented on HADOOP-10635:
---------------------------------------------

How about making the SR algorithm configurable with SHA1PRNG as default?

Regarding the HadoopIllegalArgumentException, I'd say use JDK IllegalArgumentException and
pass the GSEx as cause.

Please add a simple testcase.

> SRN generators are provided by crypto libraries. the CryptoCodec gives access to a crypto
library, thus it makes sense to expose the SRN generator on the CryptoCodec API.
