If the key generation process uses a predictable random number source, then even if the key length is nominally 2048 bits, its effective entropy may plummet to dozens of bits or even single digits.

UnverifiedThe Mersenne Twister algorithm is not a cryptographically secure random number generator; by observing enough (typically 624) consecutive outputs, one can fully reconstruct its internal state and predict subsequent random numbers.70% similarUnverifiedA pseudorandom function takes a key and an input and outputs a value that appears random but is completely deterministic; the same key and input always produce the same output, and to an observer who does not know the key, the output is computationally indistinguishable from true random numbers.69% similarUnverifiedcrypto.getRandomValues() guarantees unpredictability but not absolute statistical uniformity; uniformity must still be ensured through post-processing such as rejection sampling. It is also constrained by a limit of 65536 bytes per call.68% similarUnverifiedWhen one component of a system already has randomness, stacking a probabilistic component on top of it exponentially amplifies debugging difficulty.64% similarUnverified以Shor算法分解2048位RSA密钥为例，估算需要约2000万个物理量子比特和数小时容错运算，期间需维持逻辑错误率低于10⁻¹²量级63% similar
