CONFIG_UPDATEHUB_DOWNLOAD_SHA256_VERIFICATION

SHA-256 on download

Type: bool

Help

Enables SHA-256 verification of data stream while downloading.
Notice that it does not check whether the image written to a
storage is still valid, it only confirms that what has been
downloaded matches the server side SHA.

To check if the data written to permanent storage matches the SHA
simultaneously, enable "Both download and flash verifications"
option.
