Choice of parameter for certificate APIs ?

[DannyBackx]

Hi,

As you may have noticed (see viewtopic.php?f=2&t=13716) I am working on certificate stuff.

Why do the esp32 APIs work with a certificate in PEM format instead of the (e.g.) mbedtls_x509_crt * ?

If you use more than one module that requires this, then the all the conversions will happen multiple times. Looks unnecessary. An example is esp_https_ota(). Shouldn't functions like that have a

Code: Select all

  const mbedtls_x509_crt *certificate

as one of the fields in the esp_http_client_config_t parameter, instead of

Code: Select all

  const char *cert_pem

Small addition to my post : I can find "_pem" in these include files (excluding components/mbedtls) :

Code: Select all

components/esp_https_ota/include/esp_https_ota.h
components/mqtt/esp-mqtt/include/mqtt_client.h
components/esp_http_client/include/esp_http_client.h
components/esp_https_server/include/esp_https_server.h
components/esp-tls/esp_tls.h

Thanks,

Danny
