Hi greycon,
Currently, I use the key to sign some data, and I am storing a public key.

Hi MicroController,

Is there an automatic mechanism to update certificates ?
I currently have certificates stored in a dedicated data partition so they can be updated. So I need a solution to update certificates.

Thanks for your reply.
Best regards,

Hi,

I have a problem for certificate key https with esp-idf V5.1.3. I have hardcoded the certificate key in the code, but after a period of time, the certificate key in my tool becomes outdated. I need a solution for this issue.

- I'm using an ESP32-S3 connected to an EMMC04G-MK27-A01C. The write speed is 3.7MB/s and the read speed is 11.4MB/s. I'm not sure if this ...

Hi,

I need to enable secure boot and encrypt flash using code, not modify in menuconfig.

Thanks for your support!
