Konqueror Service Menu - Decrypt Tarball

Hello,

I often create tarballs (.tar.gz) files and encrypt them using gpg. What I
end up with is a .tar.gz.asc file.

To extract the contents of this .asc file, I (using konqueror):
1. Click on the file and enter my passphrase. This creates the .tar.gz file.
2. Right click on the .tar.gz file and use Extract->Extract Here


What I am trying to do is fold these two steps into one by creating a
Konqueror Service Menu. I have successfully created the entry and the
associated mimetype, etc.

I use the following command (which works from the command line):
gpg --decrypt %F | tar zxC %D -f -

What this does is decrypts the file (absolute path via %F) to stdout and
pipes the contents (the .tar.gz) to tar.

My problem is that in my ~/.xsession-errors I get the following error:
gpg: cannot open `/dev/tty': No such device or address


I'm not sure why gpg what /dev/tty, perhaps its for pinentry-qt? If you use
this command in a terminal a pineentry-qt appears so you can enter in your
passphrase.

Anyone know what I can do to make this work?

Thanks,

Alvin

Of course, 10 seconds after posting this I RTFM and find the answer!

The gpg error can be avoided by using the --no-tty options. So the command
will look like:
gpg --no-tty --decrypt %F | tar zxC %D -f -

Now this works wonderfully. I simply right click on any .tar.gz.asc file and
Actions->Decrypt and Extract Here

Sorry for the noise.

Your welcome.

I have created an RPM so this service can be easily (re)installed.

I have one problem though. For this service to work correctly, I had to
create a pgp-tarball.desktop mimelnk file. This mimelnk file contains the
filter that decides which files get the "Decrypt and Extract Here" Action
context.

The problem I am having is that I loose the Kgpg binding with my custom
pgp-tarball.desktop file. In other words, when I left-click on
the .tar.gz.asc file, I get the dialog box that prompts for the app to use.
What should happen is that kgpg should be launched, which is what happens
when I click on any other .asc file. I can easily fix this by going into
the control center and add kgpg as an app for the pgp-tarball file
association.

What I would like to do is to do this automagically through the RPM. This
way the RPM will be fully complete.

My investigations show that I need to edit the kgpg.desktop file and add the
application/pgp-tarball to the mime type list. However, I cannot find a
command line program that will make the association. A command line program
would make this a lot easier, especially for when the RPM is uninstalled.

Do you know of a command line program that can edit the mimetypes (rather
than using the GUI)?

Thanks,

Alvin

I couldn't find anything myself, so I have the RPM editing kgpg.desktop
using sed. sed does the trick. It will add application/pgp-tarball when the
RPM is installed and remove it when the RPM is uninstalled. This seems to
be working well.

Alvin,

your question went way beyond my limited Linux knowledge, but it is kind of fun to sit and watch you solve your problems on your own <G>

I put the RPM for this service menu on kde-apps.org. If anyone is interested
in it, you can check it out here:

Just in case knode chops the link, here's the tinyurl version:
