What is QRNG.io?
QRNG.io is an educational hub created by iQrypto to explain quantum random number generation, entropy, and QRNG applications in cybersecurity.
Why randomness matters for security
Encryption keys, session tokens, authentication challenges, and post-quantum cryptography all depend on unpredictable random numbers. If the entropy source is weak, the security system can fail even when the cryptographic algorithm is strong.
Keys & tokens
Cryptographic keys, nonces, and session tokens are only as strong as the randomness used to create them.
Secure communications
Protocols that establish confidentiality and authenticity depend on unpredictable values at every handshake.
Post-quantum readiness
Modern and post-quantum schemes still rely on high-quality entropy to seed key generation.
