About This Generator
This random number generator uses the Web Crypto API (crypto.getRandomValues()) for cryptographically strong randomness, making it suitable for passwords, lottery draws, scientific simulations, and any application where true randomness matters. Unlike Math.random(), the Crypto API provides unpredictable values seeded from system entropy.
