I have a unique need here and hope there is someone out there that might be of help. There is a backend server that will send an x509 certificate and private key (as strings) after the mobile apps on-boarding process. Additionally, the app includes an AWS SDK that is used to talk to their IoT system. This SDK requires PKCS12 certificate format to pass authentication. (I believe the common method is to have bundled the cert into the app which is not an option for me here sadly) I suspect it may be possible to use some openSSL iOS framework to do this conversion at runtime but have not personally tried it yet as my go-to is usually trying things first with Apples APIs. So my question becomes is there a way to meet this requirement using any of the security APIs or other APIs that apple has like swift-nio-ssl? Thank you very much for your time. Best, Michael
