Hi,

Are these errors from our Crypto: ECDSA sample?

Per your suggestion, we have successfully compiled our program, but the program still encounters new error messages while executing. The errors are "undefined reference to psa_sign_message" and "psa_sign_message is undefined". Could you please tell us how to address the problems

We do not yet have a reference to the PSA Crypto API in our documentation, but you can use the PSA Cryptography API 1.1 official documentation.

Sorry, I would like to ask how to use the PSA Crypto API in the project?
I can't find any steps for using this API in the document.

Yes, I think it should be fine on the dongle.
To be sure, I suggest that you try to build it for the dongle and test.

Hi,

In Crypto: ECDSA sample, the hardware platforms support nRF52840 DK, but our hardware platform is nRF52840 Dongle with PCA10059

Is this sample support nRF52840 Dongle with PCA10059?

Hi,

First of all, I recommend that you have a look at our Crypto: ECDSA sample.

This uses the PSA crypto API.
This is useful for multiple reasons:

The PSA Crypto API functionality is well documented at https://armmbed.github.io/mbed-crypto/html/index.html.
The PSA Crypto API will choose the best Crypto Library for your application. Then you can use Kconfig to enable and disable the backends you want to use.
The PSA Crypto API will also work with Trusted Firmware-M. Meaning that if you on a later point in time want to change to a nRF5340 or nRF9160, you will have an easier time.

Are you able to use the PSA Crypto API instead of "nrf_crypto_ecdsa_sign"?
