Sorry, but I don't see how this is a better solution. You then have to store two things somewhere: the hash and its signature. If the fitImage is already signed - there's no reason to have a second signature for the hash: it already comes from a trusted source. This would also inflate the size of the initramfs - not only would it need to include the cryptsetup tools but also additional tools for signature verification. Bart
