nRF9160-DK ECDSA Private key

[Gioele]

Hello!
We are trying to sign our data using ECDSA (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/crypto/ecdsa/README.html). In this example the private key is randomly generated, we need to import a personal one. How can we do that?

Hi Gioele,

We are using the PSA APIs for this sample. These APIs provide key management functions described here:

https://armmbed.github.io/mbed-crypto/html/api/keys/management.html

The sample can be modified to use psa_import_key instead of psa_generate_key so that you can use your own key.
