Entropy-Based-Randomizer

A minimal C++17 random number generator that pulls directly from system entropy sources.
On Linux/macOS it reads from /dev/urandom, while on Windows it uses BCryptGenRandom.
The library is header-only, lightweight, and requires no external dependencies.

Features

• High-quality randomness from system entropy.
• Cross-platform support (Linux, macOS, Windows).
• Header-only, just include EntropyRandom.hpp.
• Simple API:
• rand32() → random 32-bit unsigned integer
• randint(lo, hi) → integer in a given range
• randdouble() → floating-point in [0, 1)

Example

#include <iostream>
#include "EntropyRandom.hpp"

int main() {
    EntropyRandom rng;

    std::cout << "Random uint32: " << rng.rand32() << "\n";
    std::cout << "Random int [1,10]: " << rng.randint(1, 10) << "\n";
    std::cout << "Random double [0,1): " << rng.randdouble() << "\n";
}
