Secure random number generators (RNGs) are essential in cryptograph for generating keys, initialization vectors, and ther sensitive data. Thee quality of randominess directly impacts the security of cryptographic systems. Designing an effective RNG enterves commercing thae sources of entropy and ensuring unpredictability.

Sources of Entropy

Entropy sources providee the initial randominess need ded for secure RNGs. Common sources include hardware events, user interactions, and environmental noise. Combing multiplee sources can imprope entropy quality and reduce predictability.
