csr towards aws iot

[livetsMozell]

Hello, we want to do a certificate signing request towards aws iot, generating the request on the device. The reason we want to generate the request on the device is that the automatic reply from aws iot when requesting keys and certificates (docs.aws.amazon.com/.../fleet-provision-api.html is to large for a buffer in the tls layer of nrf91. 

AT command %keygen for csr seems to use to few bits in their rsa key. The requirement from aws is 2048 bits. What is the suggested method for generating a certificate signing request on 9160? 

thank you for answers

Hello, 

Yes, this should be possible as you point out. Our developers are working on an AWS IoT provisioning sample, which can be found here. Have a look at the Readme file. 

Kind regards,
Øyvind

thank you, are there any planned work to support direct use between 91 and aws's native provisioning topics?

Are there any updates on this?  I am using SDK 2.3.0.  I tried to follow the sample, but couldn't get it to work.

Hello Øyvind,
Unfortunately, I cannot get it to work with nRF Connect SDK v2.5.2. Can you please guide me through AWS Fleet Provisioning with nRF9160?
Thank you.
