... even RDSEED is masked by DBRG obfuscation
   correction: DRBG - deterministic random bit generator. you also see
   this construction referred to as key expansion, but definitely not the
   same thing as raw access to a true random number generator (TRNG). let
   me prod that hardware entropy source sample set!!

   (VIA processors with XSTORE let you do so, if you're feeling nostalgic.
   just configure as desired via MSR register bit flips and call at will!
