choice CSPRNG_GENERATOR_CHOICE: Cryptographically secure random generator

Cryptographically secure random generator

Type: bool

Help

Platform dependent cryptographically secure random number support.

If the hardware entropy support of the platform has sufficient performance to support CSRNG then select that. Otherwise, select CTR-DRBG CSPRNG as that is a FIPS140-2 recommmended CSPRNG.
