Code Signing Tool

Dear NXP community,

I have a question. Is it possible to tell the Code Signing Tool to use a specific key to encrypt an image?

Regards,

Frieder

Hello,

The Code Signing Tool automatically generates a random DEK, if the “Install Secret Key”
command is present in the CSF and CST is in encryption mode. No ability to use a specific

key instead of automatically generated one.

Regards,

Yuri.

The CST back-end source code contains code to read a pre-existing DEK key. To use it, you'll need to modify the back-end code.
