• factory_signing/factory_signing_pubkey.pem Public key used by the flashing tool for signature verification.
• firmware/fw_key.bin 32-byte firmware envelope key used for .bin.enc encrypt/decrypt. It is copied into release package as keys/firmware/fw_key.bin.

Only the key files listed above are required in this repository.
