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.
> Add a method to CryptoCodec to generate SRNs for IV

> SRN generators are provided by crypto libraries. the CryptoCodec gives access
