Feel free to share your theories on the best random number generator designs below, or send your best builds straight to the tipsline. Randomly, of course!

That means that even if some enemy understands everything about how the random number generator works, they still can’t predict the outcome.

The world’s first practical quantum random number generator (QRNG) will reportedly overcome weaknesses of current encryption, revolutionizing internet security.

For that you’ll need a true random number generator (RNG), and this open-source hardware RNG uses one of the better methods we’ve seen.

Technology Engineering Here’s how to generate a truly random number with quantum physics CURBy is available online and free to use. Andrew Paul Published Jun 12, 2025 2:01 PM EDT ...

Professor Jooyoung Lee stated, "POSDRBG is a new deterministic random bit generator that improves both random number generation speed and security, making it applicable from small IoT devices to ...

Many processes for producing these keys — such as the random number generator that's probably on your computer right now — use an algorithm that spits out a seemingly arbitrary string of numbers.
