The main problem of MBEDTLS_PSA_CRYPTO_LEGACY_RNG is that it brings in some legacy modules (entropy + ctr_drbg/hmac_drbg) which means extra ROM/RAM footprint. MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG instead simply calls to the CSPRNG which makes it definitely smaller. Signed-off-by: Valerio Setti <vsetti@baylibre.com> |
