CST Tool signature algorithm

stefano_zingari — Fri, 05 Jul 2019 08:43:42 GMT

CST Tool is used to creare a signed boot image for NXP devices, due to the fact CST Tool is not fully opensource, is anybody able to depitct which is the algorithm applied to create the image?

The most interesting part is: how are used private keys?

Goals to be accomplished are:

- Split CST tool to retrieve from remote server CRT and Private keys

- Create a "reverse" tool to verify the boot image before flashing it

Hello,

Look at the latest CST 3.2.0, which is public and is the first open source release.
