OneRNG – Open Hardware Random Number Generator
Usual caveat: Hardware RNGs don&#x27;t really solve any practical problem, and are mostly based on urban legends about cryptography, e.g. the idea that you have to constantly refeed &quot;lost&quot; entropy in an RNG.<p>The issues with RNGs usually come down to lack of use of a secure RNG, bugs within the RNG or early boot time entropy. Only the third may benefit in theory from a hardware RNG, but the devices that potentially have this problem usually don&#x27;t come with an USB port, so it doesn&#x27;t help either.
