This project illustrates the use of Intel's DRNG capabilities for random number generation.

Field guide to randomness, entropy and RNGs: PRNG vs TRNG vs CSPRNG, the NIST SP 800-90A/B/C pipeline, min-entropy, conditioning, real-world seeding failures, and why Cloudflare's lava lamps harvest entropy instead of creating it. Born from a collaborative cross-review of a YouTube thread.
