Ok. But ...

Either way there is a problem when you apply the signature. The csize cannot be 
calculated until after you generate the signature, but the signature encrypts a 
hash of the module file, which includes the csize.

So either we need to exclude the size of the signature or not include the csize 
in the hash.
