Looking for linux stm32-encoder encryption tool (binary or source)

[AD'Io.142]

I am currently trying to compile an image for a qualcomm ESC board (STM32F0xx based brushless DC controller). I manage to build the firmware up to the last step, where the firmware is encrypted using a key. To do this, the make file calls a utility, stm32-encoder. I can't find this utility anywhere, online or in the stm32 toolchain. Can anyone point me in the right direction?

Hello  @AD'Io.142 ,

I would like to sincerely apologize for the delay in replying to your post.
this question is not about motor control or MCSDK, can you tell me if you still need help and give me more details please?
Regards
