Direct Entropy Injection in ML-KEM: Understanding MakeKeyWithRandom and DRBG Bypass

At Crypta Labs, we are interested in direct applications of quantum random number generators (QRNG). This interest led us to explore how we can use our QRNG entropy directly in cryptographic operations, without intermediate processing layers. As we transition to post-quantum cryptography (PQC), it’s important to understand the need for randomness in these new algorithms. […]
