How can I recover the deleted certificate

[Khalil_Azouz]

Hi,

I'm using SE050 Secure Element, and I think I deleted the device certificate by using DeleteAll API.

Is there any way to recover these Certificates?

Hi @Kan_Li ,

Thank you for reply,

I also have another question, Is there any way to use "Se05x_API_DeleteAll" Api without removing those certificates?

Regards,

Hi @Khalil_Azouz ,

It depends. Actually only secure Objects that are trust provisioned by NXP are not deleted (i.e., all objects that have Origin set to ORIGIN_PROVISIONED), while this attribute is updated during applet runtime for Secure Objects of type AESKey, DESKey, HMACKey, ECKey and RSAKey only and does not get updated for other object types. so better save the certificates before issuing the DeleteAll command. You may use the following demos for that purpose.

Hope that helps,

Have a great day,
Kan

Hi @Khalil_Azouz ,

I think you might have to go through the EdgeLock 2GO service to restore them, please kindly refer to "se05x_mw_v04.01.00/simw-top/doc/nxp_iot_agent/doc/introduction.html#offline-provisioning-of-secure-objects" and https://www.nxp.com/products/security-and-authentication/secure-service-2go-platform/edgelock-2go:ED... for details.

Hope that helps,

Have a great day,
Kan
