How to select /dev/random or dev/urandom in the code in Android? @D.W.: Thanks for your recommendations. In fact I'm not planning to use dev/random as a seed source for a "real application". I know it depletes the entropy pool and blocks the system but I'm planning to test the randomness of dev/random and dev/urandom to check "how much" security advantage the former file provides over the latter one. |

How to select /dev/random or dev/urandom in the code in Android? Thanks again David, I guess I'll need to build Android platform for both dev/random and dev/urandom as the selected seed source and then install on my device. Hope I can switch between dev/random and dev/urandom on the Android source code. It feels like Android will permit because both dev/random and dev/urandom exist on the Android system. On the other hand, trying on a different platform is another choice as you implied. |

How to select /dev/random or dev/urandom in the code in Android? Thanks David. As you pointed out, it's written on the documentation that: "By default, instances of this class will generate an initial seed using an internal entropy source, such as /dev/urandom. This seed is unpredictable and appropriate for secure use." However what I'm planning to do is, to generate random numbers using SHA1PRNG with seeds from dev/random and dev/urandom, then check the obtained random numbers with randomness tests for comparison. As the documentation says a blurry exp like "from such as /dev/urandom" it's not clear which file is used generate the seed. |
