Security manager and how to enable the encryption

[Hussain]

Hi ,

I am using the code that is built-in and I want to know about the Security manager. I want to see the encryption is enabled or disabled. What is the command? If I want to work with the cryptography function how can I use them in the main function?

Thank you for your reply. How can I check the key size in nrf5 SDK? How can I transport the key during the pairing? How can I see the key status in the program?

Using the Peer Manager, you set the min/max key size as input to pm_sec_params_set().

    sec_param.min_key_size      = SEC_PARAM_MIN_KEY_SIZE;
    sec_param.max_key_size      = SEC_PARAM_MAX_KEY_SIZE;

What do you mean by transport the key, and key status ?
