Hello. This may sound like a phenomenally idiotic question, but I'd like to somehow send an email to a friend with a broken signature to make it look as if the message has been modified in transit. I'm teaching him the ins and outs of PGP and he'd like to see what it's like when a signature is invalid.
What's the simplest way to do this, given that it's going to be a one-off occurence? Perhaps there's some way to save a message to disk just after it's been signed but just before it's sent so that I can modify it in a text editor? thanks, MC
