Thanks for the fast reply, well thats like i thought
but i must be missing something - what is actually
signed within this multipart ?
I thought it was :
Part 1 Content-Types
Part 1 Data
Part 2 Content-Types
Part 2 Data
or do i miss something here ? I dont think the
boundarys are signed to, or are they?
Because i tried to verified such a message as i said
with gpg, i pasted the 1 Part and the 2 Part together
and tried gpg --verify sig.txt data.txt, but i always
had a bad signature.
