F29H85X-SOM-EVM: ECDSA signature verify.

Part Number: F29H85X-SOM-EVM

Hi,

In the example provided for ECDSA signature generation and verification, I am unable to find where the signature is being verified in the AsymCrypt_ECDSAVerify API.

Does the AsymCrypt_ECDSAVerify API verify r == v?

Thanks and Regards,

Shashank

    Hi Shashank,

    In the AsymCrypt_ECDSAVerify API, the verification happens by calling the cri_pke_ecdsa_verify_hash API which in turn calls the  __pke_ecdsa_verify API.

    You can go through these APIs to understand the flow for signature verification.

    Thanks and Regards,
