...
should be encrypted and which portions should not. Because of the MIME body
part structure, it might be easier for a user to identify which body parts of
a
content should be encrypted, but I do not think that is is obvious that there
is such a requirement. However, I do see a need to support forwarding which
preserves the signature from the original sender.
Actually would it be possible for different body parts to be encrypted for
different principals. I can envision applications where someone might send me a
multi-part message where some of the parts are encrypted, but not for me.
Instead
I forward these parts (perhaps with additional information) to other parties
who
can decrypt them.
