In order to use "psa_" crypto functions I use "CONFIG_NRF_SECUIRTY=y". I am also using mbedtls for TLS1.2 networking via external WiFi module
By using NRF Security, the project will no longer build
1 - The "mbedtls_ctr_drbg_*" functions are no longer configured because CONFIG_MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG is defined which forces MBEDTLS_RNG_C to NOT be defined. Unfortunately Zephyr build needs that since it uses ctr_drbg in random subsys. It seems I could turn that off perhaps, but shouldn't zephyr use the external rng if defined?
2 - The "pk_wrap" file references mbedtls_pk_write_pubkey which isn't defined because PK_WRITE_C isn't defined, but adding CONFIG_MBEDTLS_PK_WRITE_C to the project config doesn't fix that since the header generation ignores that for some reason
3 - I'd also like to use MBEDTLS_DEBUG but the build forces that to 'n'
it seems CONFIG_NRF_SECURITY=y can't work out-of-the-box. ?
