WebThe default random number generator algorithm for these versions of Windows is AES_CTR_DRBG from SP800-90a. DRBGs rely on entropy to provide secure random number generation. Good entropy typically depends on hardware and other factors to ensure its randomness. Most applications rely on the platform to provide secure random … WebThe security strength of DRBG is determined by the hash algorithm used. This implementation only supports hash functions whose output length is 256-bit or 512-bit. SHA-1 is deprecated for its insecurity. Only SHA-256 …
