minus-square@MystikIncarnate@lemmy.calinkfedilinkEnglish1•2 years agoWell, it’s an fTPM, aka software, and AFAIK, no software can truly have a random RNG. So it might be very good pseudo random at best.
minus-square@argv_minus_one@beehaw.orglinkfedilinkEnglish1•2 years agoIt could be only mostly firmware, with a hardware RNG. If not, and it uses a CSPRNG, then I don’t see much point in using it at all. Linux already has its own CSPRNG.
