For that reason, The key exponent needs to be generated using a cryptographically-protected pseudo-random selection generator (CSPRNG) like the WorldWideWeb Consortium (W3C) Cryptography API (disclosure: I am certainly one of 12 contributors to that spec on Github), so that there's significantly less likely a chance that an attacker could forecast that worth, because the random bits that make up that range are sourced from a variety of areas from your local machine, and from procedures that don't transmit that entropy details online (assuming the software package you happen to be utilizing is safe in addition to a Protected CSPRNG).
