var SigningKey []byte
SigningKey is the public key used to verify signed upgrades. It must match the private key used to sign binaries for the built in upgrade mechanism to accept an upgrade. Keys and signatures can be created and verified with the stsigtool utility. The build script creates signed binaries when given the -sign option.
