NRF Crypto Lilbraries in NRF Connect

[matematiconaocalculadora]

Hello, hope to find you well. I'm a beginner involved in a project that's migrating from the old SDK to NRF Connect (VSCode). The project uses nrf_crypto.h and nrf_crypto_rng.h from the old SDK. Can someone please help me or give a direction on how to use it in NRF Connect? Thanks in advance.

Hi,

Thanks for checking with us. Crypto Libraries (nordicsemi.com) is still partly available on nRF Connect SDK(NCS).

At the same time, NCS also provide support for Platform Security Architecture (PSA) API. Samples of usage can be found in Cryptography samples (nordicsemi.com).

Feel free to ask if you have more specific questions. Good luck to your development!

Best regards,

Charlie

Hi, Charlie. Thank you so much for answering. More specifically, I believe I need to access the NRF Crypto frontend. The sdk_config.h contains:

#ifndef NRF_CRYPTO_ENABLED

#define NRF_CRYPTO_ENABLED 1

#endif

In our project, we use nrf_crypto_rng_vector_generate(), from nrf_crypto_rng.h, for example.

Is there a way to use this in NRF Connect? If so, how can I set the flag in prj.conf?

Once again, thanks in advance.

I think the following sample shows exactly what you need:
