Here is a short story centered on this tool and its technical quirks. The Midnight Flash
For security-sensitive deployment cycles, the tool interfaces directly with hardware-level security fuses (eEfuses). During an encrypted download cycle, the utility pushes raw plaintext firmware to the volatile memory of the chip, which leverages its internal hardware key to encrypt the blocks before committing them permanently to the external SPI flash memory. If no encryption key is actively written to the eFuse bank, the software can automatically randomize an immutable key block and commit it to the silicon fabric.
