Nordic Specific Tool for generate ECC Keys(Public & Private) pair.

[Srinivas V]

Hi Team,

1. Is there any tool to generate the ECC Key(Public & Private) pair for validating digital signature things. So that we can use the same and we will implement the Hash followed by ECC mechanisms.

2. Is there any ECC Key Exchange mechanisms for OTA point of view.

It could be very helpful to us in final product development. 

Regards,

 Have you looked at nrfutil?

 Take a look at the ble_app_hrs example which uses LESC to secure the BLE connection. LESC uses an Elliptic Curve Diffie-Hellman (ECDH) key agreement to derive encryption keys. E.g. here is the message sequence chart for LESC pairing,numeric comparison https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.s132.api.v7.0.1%2Fgroup___b_l_e___g_a_p___p_e_r_i_p_h___l_e_s_c___b_o_n_d_i_n_g___n_c___m_s_c.html
