ECDSA verification on KW45b41zevk

[soyguardian]

Hello all,

I need support regarding a crypto library that uses on-chip hardware acceleration. I could not find any useful documentation about that library and functions.

Board: KW45B41Z Evaluation Kit with Bluetooth® Low Energy
Environment: MCUXpresso SDK 2.12.5

I want to use the ECDSA verification function (accelerated with the EdgeLock® Secure Enclave) these functions are called ECDSA_VerifySignature(...) and ECDSA_VerifyMessageSignature(...) in the SecLib library from the framework in a demo application (kw45b41zevk_digital_key_car_anchor_freertos). The code compiles, but the return value is: bad parameters. Perhaps I do something wrong in the usage of these functions.

I noticed that their source code is not in the SecLib_sss.c (for other elliptic curve functions this is the case).

Thanks in advance for any help.

Hello,

Hope you are doing well. Could you please help us with more information about how are you integrating the code to the SDK example?

Do you have any compilation error or warning?

I just sent you a private message.
