Unable to encrypt gedit text files etc with PGP

Per https://answers.launchpad.net/ubuntu/+source/gedit/+question/171833 seahorse-plugins in oneiric does not provide the needed gedit plugin. This is because The plugin had not been updated to Gtk3 yet. This same question describes how a to register an external tool to call the gpg command line.

Gedit does not have an official PGP/GPG plugin. The plugin registry page http://live.gnome.org/Gedit/Plugins does not list a PGP/GPG plugin.

Hi, thanks for the quick response. I followed the instructions as the post stated, but got the error:

gpg: Invalid Option "--no-tty-"

The stdin arg (-) is concatenated to the option (--no-tty). Add a space after the y
  --no-tty -

Awesome, it worked! I'm still a little confused though. I ran clearsign, and this happened:

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

test 123
-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.4.11 (GNU/Linux)

EwgQN//jZLzW2kQd8joBAJkAPrMWccZfWcNCi6yK2b+m92Hw8wUCoFdFiH8u0Q+H
=Hq/A
-----END PGP SIGNATURE-----

And the message that was to be encrypted is shown under Hash: SHA256? Am I missing something?

Thanks

There is one or more additional steps you may want to take. This command clearsigned text that could then be pasted into an email or sent as a file.

You can create other commands like this one by replacing the --clearsign option with another option.
The --decrypt will decrypt will the open file
The --encrypt will encrypt the open file
So you might want three different commands.

OK, I think I understand. So the part I put in the email would be underneath the test123 section:

-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.4.11 (GNU/Linux)

iF4EAREIAAYFAk9Q75YACgkQAklLQBHXVRJB/QEAnJOyhSAWQZ63V5h+CU3zBFMy
EwgQN//jZLzW2kQd8joBAJkAPrMWccZfWcNCi6yK2b+m92Hw8wUCoFdFiH8u0Q+H
=Hq/A-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.4.11 (GNU/Linux)

iF4EAREIAAYFAk9Q75YACgkQAklLQBHXVRJB/QEAnJOyhSAWQZ63V5h+CU3zBFMy
EwgQN//jZLzW2kQd8joBAJkAPrMWccZfWcNCi6yK2b+m92Hw8wUCoFdFiH8u0Q+H
=Hq/A
-----END PGP SIGNATURE-----
-----END PGP SIGNATURE-----

This would be the encrypted test123 correct?

Also tried the --decrypt/--encypt as follows:

gpg --encrypt --no-tty -

but this error came up:

gpg: Sorry, no terminal at all requested - can't get input

Bit confusing on the last post, just enter the text encrypted under test123:

-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.4.11 (GNU/Linux)

iF4EAREIAAYFAk9Q75YACgkQAklLQBHXVRJB/QEAnJOyhSAWQZ63V5h+CU3zBFMy
EwgQN//jZLzW2kQd8joBAJkAPrMWccZfWcNCi6yK2b+m92Hw8wUCoFdFiH8u0Q+H
=Hq/A
-----END PGP SIGNATURE-----

oh dear. I forgot that those command need password and key selection. This can still be done using an external tool, but something like zenity is needed to collect the input and key selection. Let me think about this for a day because I think this needs a helper script that I believe I can write.

That would be great! Thank you. And just so I'm sure before I send an email, the PGP encryption under test123 is the encrypted message, should I just copy and paste to an email?

Thanks

Yes. you could just paste the text into the email. Now if this is just about email, you may not need a gedit plugin. Evolution already support pgp/gpg operations. Thunderbird uses the enigmail plugin to encrypt/decrypt and sign. You might not need a gedit plugin if you are not working with encrypted files on disc.

I appreciate all your help.

Another alternative would be geany (universe repo) and geany-plugins which incl. geany-plugin-pg.

I had to fight a bit to find the right syntax in the external tools menu, so I posted it to AskUbuntu: http://askubuntu.com/questions/116996/how-do-i-encrypt-decrypt-file-within-gedit

Some autopromotion/request for feedback:
http://pietrobattiston.it/gedit-crypto

(notice I developed this also because I was not able to use the "External tools" method without including in clear the password for my key - which I didn't want to).
