Suggestion for epa-mail-mode

[Richard Stallman]

epa-mail.el defines these keys:

    (define-key keymap "\C-c\C-ed" 'epa-mail-decrypt)
    (define-key keymap "\C-c\C-ev" 'epa-mail-verify)
    (define-key keymap "\C-c\C-es" 'epa-mail-sign)
    (define-key keymap "\C-c\C-ee" 'epa-mail-encrypt)
    (define-key keymap "\C-c\C-ei" 'epa-mail-import-keys)
    (define-key keymap "\C-c\C-eo" 'epa-insert-keys)

I suggest also defining C-c C-c C-d, etc,
because a sequence of all control chars is easier to type.

Is there any overall documentation of epa mode?
I want to try it, but I can't see how to use it.

Since C-c C-c is currently bound to mail-send-and-exit, using C-c C-c as
prefix will be a significant change.  Do you have any other key
sequences in mind?

See "(epa) Top" for epa-mode and "(epa) Mail-mode integration" for
epa-mail-mode.

I suspect this is a typo on Richard's side.  He probably meant `C-c
C-e C-d', `C-c C-e C-v', etc.

Aha, I see.  Thanks.  Done as r100904.

I wonder if we should also make pgg obsolete. When I raised this issue
over two years ago, this was the agreed plan. As far as I know, there's
only one file in Emacs that uses pgg -- allout.el. Its author said he
would find time to change to epg but nothing seems to have happened in
the past few years.

i've looked at migrating from pgg to epg, but there are some
intricacies and i hadn't found the time.  i'll have an opportunity to
look at it again over the next month, and will try to make the
migration.

i also have a few change pending release (including making C-h as the
terminal part of an allout keybinding optional - default off), and
have to look at converting allout to use define-minor-mode. there's
another place where the intricacies i put into the allout minor mode
implementation are getting in the way, but i guess they warrant
clean-up.

i'll be working on it all in a few weeks, with priority on the pgg ->
epg migration.

(ps - i don't keep up with emacs-devel, but do have an arrangement so
i'm alerted when allout is mentioned.)

Thank you for fixing allout.el for epg ;)

Kind regards,

thanks, leo.  i'm genuinely sorry it took so long.

in fact, there were some substantial features i had to trade-off in
the transition.  allout is more cumbersome and error-prone for dealing
with symmetric encodings for numerous encrypted entries in a file,
because i had to let go of encryption passphrase validation and
hinting.  that comes in exchange for significantly less insecurity due
to no handling of passphrases in emacs code.  instead, as always when
using epg with GnuPG version 2, all passphrase handling is outside of
emacs, in gnupg's gpg, gpg-agent, and pinentry, which i expect are
drastically less vulnerable.

it is for that reason that i was ultimately willing to forego those
features, though i wish i could have more control without greater
vulnerability...

Is it? The key is it is done ;)

Many thanks for the hard work. That looks like good compromise.

    I suggest also defining C-c C-c C-d, etc,

As people guessed, I meant C-c C-e C-d, etc.
