CONFIG_NRF_SECURITY_RNG

Random Number Generator support

Type: bool

Help

The Random Number Generator support in nRF Security provides a
Pseudorandom Number Generator, PRNG.
The Pseudorandom Number Generator is seeded by a True Random Number
Generator, TRNG, available in hardware.

Direct dependencies

ENTROPY_HAS_DRIVER && MBEDTLS_LEGACY_CRYPTO_C && NRF_SECURITY

(Includes any dependencies from ifs and menus.)
