[cryptography] Intel Security Driver and AVX CPUs (rdrand)

Hi All,

For some time, Intel has offered a Security Driver for Windows [1]. It
basically allows us to use the 810 chipset and friends as a PRNG
source via a CSP:

  if(CryptAcquireContext(&hProvider, NULL, INTEL_DEF_PROV, PROV_INTEL_SEC, 0))
  {
     CryptGenRandom(hProvider, size, block);
  }

Does anyone know if Intel is shipping an updated driver which
wraps/includes rdrand from AVX?

Jeff
