I am able to flash the certificates on siffs partition and access the certificates using file handling but how do i load then for SSL server certification and esp_http_client_config_t.

I was previously embedding the certificates into the firmware using the components.mk file like this

Code: Select all

COMPONENT_EMBED_TXTFILES = device_cert.pem

and then using them like this

Code: Select all

extern const uint8_t device_cert_pem_start[]   asm("_binary_device_cert_pem_start");
extern const uint8_t device_cert_pem_end[]   asm("_binary_device_cert__pem_end");

But I don't know how to load them from the spiffs partition in the flash memory. Can somebody please help me out ?

Thanks

Have a look at this post. I asked for a similar purpose:

In my case, I ended up copying the certificate data into RAM and passing them to the APIs.

It looks like you may have to do the same:
