This patch set implements crypt_opportunistic_encrypt. This option allows mutt to automatically turn encryption on and off based on the message recipients.
When emailing one person, a hook turning on crypt_autoencrypt works well enough, but for multiple recipients it breaks down. The hook will turn on encryption if one of the recipients matches the hook, whether the other recipients support encryption or not. This patch allows mutt to make the decision for you. It modifies the various find_key methods to query whether all recipients have a crypt-hook or have a key that can be automatically determined. I have tested this for classic pgp and gpgme modes, but don't currently use smime. (The patch is much less invasive for smime, but feedback on whether that works properly would be appreicated.) This is my first large patch to mutt, but I think it would be useful and many people would take advantage of it. I welcome feedback and hope I can improve it enough to be accepted. -Kevin crypt-gpgme.c | 42 +++-------------- crypt-gpgme.h | 4 +- crypt-mod-pgp-classic.c | 4 +- crypt-mod-pgp-gpgme.c | 4 +- crypt-mod-smime-classic.c | 4 +- crypt-mod-smime-gpgme.c | 4 +- crypt-mod.h | 3 +- crypt.c | 25 +++++++++- cryptglue.c | 8 +- mutt_crypt.h | 4 +- pgp.c | 31 +------------ pgp.h | 2 +- smime.c | 34 +-------------- smime.h | 2 +- crypt-gpgme.c | 14 +++-- crypt-gpgme.h | 4 +- crypt-mod-pgp-classic.c | 4 +- crypt-mod-pgp-gpgme.c | 4 +- crypt-mod-smime-classic.c | 4 +- crypt-mod-smime-gpgme.c | 4 +- crypt-mod.h | 2 +- crypt.c | 4 +- cryptglue.c | 16 ++++-- mutt_crypt.h | 12 +++- pgp.c | 4 +- pgp.h | 2 +- smime.c | 4 +- smime.h | 2 +- crypt.c | 20 ++++++++ mutt_crypt.h | 3 + pgp.c | 17 +------ crypt-gpgme.c | 105 ++++++++++++++++++++++++++++----------------- pgp.c | 42 ++++++++++------- pgp.h | 2 +- pgpkey.c | 24 ++++++++-- smime.c | 6 +- crypt.c | 30 +++++++++++- mutt_crypt.h | 10 +++- send.c | 2 +- compose.c | 17 +++++++ init.h | 8 +++ mutt.h | 1 + send.c | 8 +++- 43 files changed, 307 insertions(+), 239 deletions(-)
