Hi Jim,

sorry for the late reply as i didnt rceive any notification on post.
i didnt make any progress,. as its a complete blocker.as i my code is not perfect , so i am trying to decrypt the azure nonce challenge, i tried azure_sdk_for_C in that hsm_client_tpm_import_key, insert_key_in_tpm which decrypts the nonce challenge which is based on TSS, but i didnt get the exact method in wolftpm to decrypt the nonce challenge as per TSS.
so i would receommend you to share the code which can meet this requirement.

Regards
nandish

Hi nandish

Thanks for your interest in the wolfTPM for ESP32.

I don't think we have an Azure example but I'd like to help.

Can you share more details about your project and provide some sample code?

Thank you

Jim
