https://devzone.nordicsemi.com/f/nordic-q-a/69841/modem-key-managementHello I am using the APII described here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/include/modem/modem_key_mgmt.html to add keys to the modem. I use the write() function to write keys and then to read and compare.

Does it return a key at all when reading certificates 2 and 3, or does it return some error instead? I suspect the problem is the same as in your other&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/69804/help-with-nrf9160-connecting-azure">case</a>, since certificate 0 returns correctly, while certificates 2 and 3 doesn&#39;t. You&#39;re not able to read certificates 1, 2 and 3 (client certificate, client private key and pre-shared key) for security reasons.</p> <p>Best regards,</p> <p>Marte</p><div style="clear:both;"></div>
