What's the best way to store and use multiple certificates in a WICED device?  This isn't necessarily a requirement that I have, but a reasonable use-case would be:

- a self-signed CA cert for securing and authenticating connections to proprietary servers

- a self-signed cert (i.e. no root signing authority, or a separate one from the above) for the locally running webserver

Would the best option be to put additional certificates in the application section of the DCT?

Thanks!

Hi,

The DCT could be expended to include user data as well. Wiced uses to store header, mfg_info, certificates, and config information and the rest of the DCT could be used by the user application. Size of the DCT depends on the platform. For example STM32F1xx is 8K and STM32F4xx is 16K.

Please check the ...\Wiced\Platform\include\platform_dct.h and expand it as needed.

Thank you, seyhan!  I'll plan to use the app section if I need to use multiple certificates.
