No. This would matter if entropy was somehow directly provided to applications. But no modern system does this. Instead, entropy is hashed into a key for a keystream generator (based either on a hash function, a MAC, or a stream cipher).<p>That&#x27;s the entire point of a DRBG†: to securely incorporate inputs of wildly varying randomness into an RNG whose future outputs are as difficult to predict from past output as keys are to recover from ciphers.<p>To somehow &quot;predict&quot; the output of the system from its input, you would need to be able to work back from the output of a cryptographic keystream generator <i>back to its key</i>. If you can do that, forget the RNG: you&#x27;ve broken most modern cryptography.<p>† <i>and even prior to this proposal, that&#x27;s what the LRNG implemented</i>
