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?

Hi Sigurd,

I mean that in ble there are phases of pairing and bonding. During these phases it establish a Long term key or symmetric key. How can I see or observe the key or the function which is taking care of it in the code? nrf5

The Peer Manager and the SoftDevice handles this for you. The LTK generation is taken care of by the SoftDevice. LTK can be accessed when you receive the BLE_GAP_EVT_AUTH_STATUS event from the SoftDevice.

Any keys generated and/or distributed as a result of the ongoing security procedure will be stored into the memory referenced by the pointers inside the p_sec_keyset used in sd_ble_gap_sec_params_reply(). The keys will be stored and available to the application upon reception of a BLE_GAP_EVT_AUTH_STATUS event. The Peer Manger( security_dispatcher.c) handles this, and will store the keys for you when you bond with a device.
