PRNG: True Hardware Entropy & Secure Randomness

PRNG generates cryptographically secure random numbers using real-time hardware entropy harvested directly from your device's physical sensors.

Unlike standard software-based generators that rely on predictable mathematical algorithms, PRNG captures microscopic physical fluctuations to build a pool of true
randomness. This raw entropy is conditioned through an HMAC-DRBG (Hash-based Message Authentication Code Deterministic Random Bit Generator) — the industry standard
for professional cryptographic systems (NIST SP 800-90A).

NEW IN VERSION 1.1.0
* Professional Exporting: Instantly copy entropy samples as Hex or Base64 for use in external cryptographic applications.
* NIST Statistical Test Suite: Prove the quality of your randomness. Run on-device statistical tests (Monobit, Runs, Frequency) to verify the output against NIST
standards.
* Real-time Visualization: Monitor your entropy pool through a dynamic Byte Distribution Histogram.
* Batch Generation: Generate up to 10,000 numbers in a single pass for large-scale sampling.
* Source Customization: Toggle specific entropy sources (Accelerometer, CPU Load, Thermal) to suit your security requirements.
* Security Audit Log: Complete provenance tracking for reseed events and generation history.

KEY FEATURES
* True Hardware Entropy: Samples physical data from CPU thermal variance, battery voltage micro-variations, system load patterns, and high-resolution jitter.
* Eliminate Modulo Bias: Uses advanced rejection sampling to ensure every number in your chosen range has an exactly equal probability of selection.
* Live Quality Monitor: A real-time dashboard shows entropy pool health (Low / Medium / High) so you know exactly when your device has reached peak randomness.
* Advanced Diagnostics: Deep-dive into DRBG internal states, pool metrics, and per-sensor activity counters.
* High Precision: Supports both multi-range Integers and full-precision Floating Point modes.

USE CASES
* Cryptographic Seeding: Generate high-entropy seeds for security keys and cold storage.
* Security Research: Verify RNG quality and study entropy distribution on different hardware.
* Gaming & Lotteries: Ensure absolute fairness in range-based selections.
* Statistical Sampling: High-volume data generation for simulations and scientific research.

TECHNICAL & PRIVACY STANDARDS
* Air-Gapped Security: No internet connection required. No data ever leaves your device.
* Zero Tracking: No ads, no analytics, no permissions except for hardware sensors.
* Transparent Implementation: Open standard implementation based on NIST SP 800-90A.

Note: Entropy quality reflects estimated bits per byte. Quality may vary based on environmental stability; the HMAC-DRBG fallback ensures your output remains
statistically sound even in stable thermal conditions.
