Cryptographic RNG vs. Standard Pseudo-RNG Comparison
Why KitWharf uses the hardware-backed Web Crypto API instead of standard Math.random().
| Feature & Metric | crypto.getRandomValues() (KitWharf) | Math.random() (Standard JS) |
|---|---|---|
| Entropy Source | Hardware OS entropy pool (/dev/urandom or Windows BCrypt) | Pseudo-random algorithm (e.g. xoshiro128+) |
| Predictability & Bias | Cryptographically non-predictable; Zero modulo bias | Predictable once internal state seed is observed |
| Security Suitability | Suitable for cryptographic keys, raffles, lotteries, and games | Never suitable for contests or sensitive generation |
| Client-Side Privacy | 100% computed inside local browser hardware | Local browser engine |
Common Random Selection & Probability Distribution Reference
| Drawing Scenario | Number of Outcomes | Probability per Outcome | Replacement Mode |

| Standard 6-Sided Die | 6 (1 through 6) | 16.67% (1/6) | With Replacement |
| 10-Option Decision Wheel | 10 Segments | 10.00% (1/10) | With Replacement |
| Unique Raffle Drawing | N Entries | 1 / N remaining | Without Replacement (Unique) |
