Hi,
A few other options:
- EPG also has the function epa-encrypt-region. It asks for a
recipient's key to use for encrypting, and does symmetric
encryption if none is selected. This could be used to selectively
encrypt certain subtrees. Especially given that...
- message-mode has functions like mml-secure-encrypt (there are lots
of others in the mml-secure-* family). These functions use the
strategy of inserting tags around the region to be encrypted. I
haven't actually read the functions, but from the outside it looks
like the tags are used to set the region, the region is
encrypted/signed, and then the tags are removed from the outgoing
copy of the message. FWIW, the tags look like (the leading # was
added by me to keep the tag from actually doing anything in this
message):
# <#secure method=pgpmime mode=sign>
As a personnal taste, I'd rather want using message-mode since it
is already part of the official GNU Emacs distribution. For the
rest, up to Carsten to see what to use.
The values of the ENCRYPT_* properties could be the key to use, or just
t. If the value is t, either the key will be pulled from a file-level
variable, or the user will be prompted for which key to use (as
epa-encrypt-region normally does).
I love this idea. That's the easiest I could think of too.
Instead of t, I think ENCRYPT_PROMPT would be a best (no need to
be an elisp expert to understand it).
Regards,
Xavier
