OpenPGP and Subject encryption

[P. Mazart]

Hi,

are there any implementations or thoughts on subject encryption
for PGP/MIME, yet?

I wonder if there might be a special trigger word inside the
encypted body part to reset or redisplay the message’s
subject (e.g. X-Msg-Subject:), so one could choose a random
Subject: Header .

Thanks
P.M.
