Unlike previously documented, enabling MBEDTLS_PSA_HMAC_DRBG_MD_TYPE does not cause the PSA subsystem to use HMAC_DRBG: it uses HMAC_DRBG only when MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_CTR_DRBG_C are disabled."

A diferencia de lo documentado anteriormente, habilitar MBEDTLS_PSA_HMAC_DRBG_MD_TYPE no hace que el subsistema PSA utilice HMAC_DRBG: utiliza HMAC_DRBG solo cuando MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG y MBEDTLS_CTR_DRBG_C est\u00e1n deshabilitados."
