gpg: signing failed: No passphrase given #29

Description

I managed to configure pinentry-mac to work nicely, but when I try to switch to pinentry-touchid I am unable to find a proper way of solving this problem. After I follow the steps provided after installation, I keep getting the following error message:

gpg: signing failed: No passphrase given
gpg: [stdin]: clear-sign failed: No passphrase given

Simplest test to reproduce:

echo "test" | gpg -vvv --clearsign

I have generated keys which have passphrases of course, but now I am unsure how to provide these passphrases to the pinentry.

Hi @nemscep I get the feeling that maybe pinentry-touchid is not falling back to pinentry-mac. Can you check the output of:

$ /usr/local/bin/pinentry-touchid -check

and also include the log content of $TMPDIR/pinentry-touchid.log ?

AndrewTriesToCode commented 1 year ago

I'm seeing this behavior too.

➜  ~ echo "1234" | gpg -as -
gpg: signing failed: No passphrase given
-----BEGIN PGP MESSAGE-----

gpg: signing failed: No passphrase given
➜  ~ pinentry-touchid -check                                 
✅ /opt/homebrew/Cellar/pinentry-mac/1.1.1.1/bin/pinentry-mac will be used as a fallback PIN program

Also fails if I select "use password". Log just shows:

➜  ~ cat $TMPDIR/pinentry-touchid.log
2023/02/07 23:26:18 main.go:118: Ready!

Same config and results as ☝️

rweir commented 11 months ago

I'm also seeing this on MacOS Ventura on an M2. It's not a new key, and the only log messages I ever get are "main.go:118: Ready!" (aside from one "main.go:348: Failed to authenticate" when I clicked the "use password" button once).

Is there some way to enable more debugging? It's not even clear the problem is in pinentry-touchid to me.

Some other random observations:

OK...while looking at my gpg-agent.conf I noticed I had put two lines in there while futzing around with easypg:

allow-emacs-pinentry
allow-loopback-pinentry

after commenting out both then running gpgconf --kill gpg-agent, then attempting to echo 1234 | gpg -as - things actually work - pinentry-touchid pops up a thing, I touch the sensor, signature works without error. No idea if this is some bizarre quirk of my system or a bug in something but maybe it helps y'all.
