Yubico Forum

Hi,

I want to use my yubikey 4 to sign git commits. I have successfully set-up a master-key (which is completely offline) and three subkeys (one for signing, authentication and encryption each) on my yubikey. Then I configured GIT to use my signing-key and to sign every commit. However, each time I try to do so, I receive the following error message:


If I use the same command on the shell directly, everything works fine:


the pinentry programs pops up, I can enter my pin and the signature gets created. I assume that the problem is with the gpg-agent's configuration, but I'm not sure.

Has anyone already configured git to use a yubikey to sign commits and how has it been done?

Cheers.

I, finally solved this issue.
I'm running gpg 2.1.11 and hence the correct program to call ist gpg2 instead of gpg. For the ease of use I have an alias in my .bashrc, such that I can use gpg. However, git search for the program in the $PATH and hence does not care about the set alias. In order to make git work, I had to configure git to use gpg2 instead. This could - once you know, that you have to do it - easily be done:
