According to the BCryptGenRandom documentation The default random number provider implements an algorithm for generating random numbers that complies with the NIST SP800-90 standard, specifically the CTR_DRBG portion of that >standard. Specifically, according to this the default value is BCRYPT_RNG_ALGORITHM which is: The random-number generator ...

I've found this attack to be poorly documented, all-in-all. Below is a technical explanation of the matter, or one can skip to the conclusion if uninterested in the details. Dual_EC_DRBG First, let me give a short description of Dual_EC_DRBG using the notation of Shumow and Ferguson (see the presentation). As a preliminary, we are working with some ...

Well, I think OpenSSL has documented this pretty well: If an alternative RAND_METHOD implementation is being used (either set directly or as provided by an ENGINE module), then it is entirely responsible for the generation and management of a cryptographically secure PRNG stream. The mechanisms described below relate solely to the software PRNG ...
