Well if you want it I'll happily supply you the source of the program I use
to sign the images but what I won't supply you are the keys so I'm not sure
exactly what you would gain from it. I've already read messages here that
have identified the standard algorithms I'm using and there's open source
for them all over the internet - it's no secret (but my keys are!)
