Gary D. Gregory updated CRYPTO-160:
-----------------------------------
Summary: Package-private class JavaCryptoRandom extends Random (was:
JavaCryptoRandom class leaks Random implementation)
> Package-private class JavaCryptoRandom extends Random
> -----------------------------------------------------
>
> Key: CRYPTO-160
> URL: https://issues.apache.org/jira/browse/CRYPTO-160
> Project: Commons Crypto
> Issue Type: Bug
> Reporter: Adrian Anderson
> Priority: Major
> Fix For: 1.1.1
>
>
> The CryptoRandom implementation class JavaCryptoRandom extends
> java.util.Random when they don't need to and without re-implementing the
> "protected int next(int bits)" method.
> The issue is that if a developer were to use the CryptoRandomFactory to
> create a JavaCryptoRandom instance and to Random wanting to use as a
> replacement for code using an instance of Random in existing code the
> implementation would fall back to the java.util.Random (inherited)
> implementation rather than the CryptoRandom (encapsulated) implementation.
> For example
> {{CryptoRandom cryptoRandom = CryptoRandomFactory.getCryptoRandom();
> //instance of JavaCryptoRandom}}
> {{Random rand = (Random)cryptoRandom;}}
> {{long randomLong = rand.nextLong(); //returns java.util.Random.nextLong(),
> circumventing SecureRandom}}
> A simple solution would be to override the "protected int next(int bits)"
> method within JavaCryptoRandom to invoke the SecureRandom "next(int bits)"
> implementation.
