- 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.
