    /dev/random is also a pseudo-random number generator. It's not safe to use the unconditioned entropy because it has varying quality so it's not exposed.

    I should think so.

    But how to tell...?

    Linus has already gone over this multiple times. /dev/random and /dev/urandom aren't seeded by a single source. They get used as one of many sources so even if one source is bad, the "bad' gets flushed out by the added entropy from other sources.

    You can seed /dev/random. In a sense, it is actually seeded by environmental noises. Using a hardware generator can be used to get the required entropy faster, especially early after boot, even more so on predictably functioning machines.

    the RDSEED instruction is supported with Broadwell hardware for seeding /dev/random.

    Since this chip was designed way before Snowden happened, this instruction most probably has nothing to do with randomness.

    Fine, as it won't be the only source for randomness to be used...

    I had asked about how Intel's RDRAND could possibly compromise entropy on StackExchange a while ago. Maybe it will be of interest to anyone seeing this article: http://crypto.stackexchange.com/ques...romise-entropy
