🔐 What is Cryptographic RNG?

A Cryptographic Random Number Generator (C-RNG) is a special type of RNG that generates unpredictable and secure random values, essential for cryptographic operations and fairness in gaming.

Unlike simple pseudo-random generators, C-RNGs use entropy sources and cryptographic algorithms to ensure that outputs cannot be predicted even if some internal state is known. They are the standard for secure key generation, digital signatures, token creation, and trusted gaming.

📌 Where Cryptographic RNG is Used

🔑 Encryption Key Generation (RSA, AES)
🎫 Security Tokens (JWT, OAuth)
🎲 Randomness in Online Gaming (Ludo, Rummy, Poker)
📱 OTP and 2FA Systems
🔐 Password Salt Creation

⚙️ Cryptographic RNG vs Pseudo RNG

Feature	Cryptographic RNG	Pseudo RNG (PRNG)
Security Level	High, suitable for sensitive applications	Low, predictable with known seed
Use Cases	Gaming, Cryptography, OTP	Simulations, Non-critical apps
Speed	Moderate	Faster
Predictability	Virtually unpredictable	Predictable if seed known
Compliant with Standards	Yes (e.g., NIST SP800-90A)	No

For RNG Certification, only Cryptographically Secure RNGs are accepted by regulatory authorities and payment gateways such as Cashfree, Razorpay, and also validated in Google Play Console for real-money gaming apps.
