PRNG — Hardware Entropy RNG

PRNG generates cryptographically secure random numbers using real hardware

entropy collected directly from your device's physical sensors.

Unlike software-based random number generators that rely on mathematical

algorithms alone, PRNG harvests unpredictable entropy from:

- CPU thermal variance

- Battery temperature fluctuations

- Battery voltage micro-variations

- CPU load patterns

- High-resolution system timestamps

This raw entropy is fed into an HMAC-DRBG (Hash-based Message Authentication

Code Deterministic Random Bit Generator) — the same standard used in

professional cryptographic systems per NIST SP 800-90A.

KEY FEATURES

→ Hardware Entropy Collection

Continuously samples physical sensor data to build a high-quality

entropy pool. The more your device is in use, the better the entropy.

→ HMAC-DRBG Engine

Industry-standard cryptographic DRBG conditions raw sensor entropy

into uniform, unbiased random output.

→ Rejection Sampling

Eliminates modulo bias — every number in your range has exactly equal

probability of being selected.

→ Entropy Quality Monitor

Real-time display of entropy pool quality (Low / Medium / High) so

you always know the confidence level of your output.

→ Advanced Diagnostics

Developer-friendly panel showing DRBG state, pool metrics, reseed

counters, and per-sensor activity.

→ Integer & Float Modes

Generate integers in any range or floating-point values with

full precision.

USE CASES

- Cryptographic key seeding

- Security research and testing

- Statistical sampling

- Gaming and fair randomness

- Education on entropy and CSPRNGs

- Verifying RNG quality

TECHNICAL NOTES

The entropy quality indicator reflects estimated bits of entropy per byte

collected. Quality may be lower in thermally stable environments (e.g.

plugged in, idle, air-conditioned rooms) — this is expected and the DRBG

fallback ensures output remains statistically sound regardless.
