Creating a Code-Signing Certificate

To digitally sign firmware images, you need a code-signing certificate and private key. For testing purposes, you can create a self‐signed certificate and private key. For production environments, purchase a certificate through a well‐known certificate authority (CA).

Different platforms require different types of code-signing certificates. The following section describes how to create code-signing certificates for each of the Amazon FreeRTOS-qualified platforms.
