-----------------------------------
GitHub user tellison opened a pull request:
https://github.com/apache/incubator-pirk/pull/7
[PIRK-2] Enhance Pallier acquisition of PRNG provider.
As suggested, this moves the spec for the secure random into the Pirk
properties file.
Note that I have left the provider commented out at the moment, to ensure
it works on a broad selection of Java runtimes, and is as close to the original
code intent as possible.
In production users would likely specify a secure system PRNG, or specify
both algorithm and provider in the Pirk properties file. Therefore I would not
object to commenting out both properties by default ;-)

>
> Key: PIRK-2
> URL: https://issues.apache.org/jira/browse/PIRK-2
> Project: PIRK
> Issue Type: Bug
> Reporter: Tim Ellison
> Assignee: Tim Ellison
>
> {{org.apache.pirk.encryption.Pallier}} has a hard coded requirement for the
> {{NativePRNG}} algorithm to be supplied by the {{SUN}} provider. This causes
> the {{test.general.PaillierTest}} to fail on IBM's Java implementation.
> The implementation should allow the provider to be configured by the
> java.security properties of the runtime to allow for provider optimizations,
> etc.
> Furthermore, the instantiation of a provider is relatively (CPU) expensive,
> so reusing the PRNG is preferable to acquiring it each time a value is
> required.
