Very precise answer, thank you.
How about a simple test to make sure it didn't break and start spitting out all zeroes. Read a few lines from
/dev/random
?I might be wrong about this but my understanding is that on Linux you'd pipe the output of this in somewhere and tell the kernel to use it for entropy, and if it gets insufficient entropy it realizes this and starts producing random bits slower. So like normally the Linux kernel samples mouse movements for randomness, and so it makes more random bits the more you jiggle your mouse. These hardware RNGs are best used for headless servers that don't have as reliable entropy at their disposal.
Yeah as long as the setup for the device symlinked its device path to
/dev/random
or you did that yourself. Stuff I used had a Java SDK
