Adding CRC header on .fota file

Can we implement CRC on .fota file?
If yes, where do we verify the CRC of the image?
I understand that .fota file has digital signature support. I would want to know if CRC check is possible in the similar manner.

No CRC is generated by the current toolset.

Validation of the image is performed during the Firmware Over-The-Air (FOTA) update process. The RSL10 Firmware Over-The-Air User’s Guide page 18 ( Chapter 5.5.2 FOTA Image Checking with the DFU Component) states that the Digital Firmware Update (DFU) component:

Checks the received signature against the calculated image hash and the public part of the signing key; if the key is incorrect, the process aborts with error code IMAGE_DNL_BAD_SIG and the downloaded image is not marked as valid.
