gpg-zip using secret key sign a zip

Question

I have the following problem.

I created a Key-Pair with Thunderbird (Engimail), then I exported the asc file, and importet it in the git bash to gpg.

Now I need to sign a zip.

Using the command:

gpg-zip --sign abc.txt def.txt

I get the message:

gpg: no default secret key: secret key not available
gpg: signing failed: secret key not available

No I've read that you can set the default key with:

gpg --default-key <keyid>

When I type this in the bash I get the message:

gpg: Go ahead and type your message ...

Now I can type and type nothing happens, when I press CTRL-D it says

 gpg: no valid OpenPGP data found.
 gpg: processing message failed: eof

I've also tried to set the default-key in the gpg.conf file, but it does not work.

Can someone help me?

Answer 1

You need to use --default-key as part of a gpg command, e.g.

gpg --sign --default-key ABCD1234 file.txt

which will both run the command (in this example sign the file with key ABCD1234) and set gpg's default key.

Update:

Actually, on my box it looks like gpg-zip is ignoring gpg's default key, so probably need to go with @Peter Harmann's answer.

Answer 2

U can try specifying the key with the -u argument. So you would use something like:

gpg-zip -u 0xFFFFFFFF --sign abc.txt def.txt

or

gpg-zip --sign --gpg-args -u 0xFFFFFFFF abc.txt def.txt
