- JoachimS 3y agoAnd very importantly, a TRNG is often not cryptographically safe and should never be directly used for security related use cases. Basically only be used to (re)seed a good CSPRNG (DRBG in NIST parlance). Another benefit of a CSPRNG is vastly higher performance than most TRNGs can achieve. A TRNG often provide kbps birate. A CSPRNG can easily deliver Many MBps, even GBps.
