How do I enable ssh access with a GPG key for authentication?

Enable the GPG subkey

1. $ cat .gnupg/gpg-agent.conf. enable-ssh-support. Optionally, you may want to pre-specify the keys to be used for SSH so you won’t have to use ssh-add to load the keys.
2. $ gpg2 -K –with-keygrip. /home/bexelbie/.gnupg/pubring.kbx. ——————————
3. $ cat ~/.bashrc. …

Why do I have to ssh-add?

ssh-add adds private key identities (from your ~/. ssh directory) to the authentication agent ( ssh-agent ), so that the ssh agent can take care of the authentication for you, and you don’t have type in passwords at the terminal.

What is ssh-add?

ssh-add is a command for adding SSH private keys into the SSH authentication agent for implementing single sign-on with SSH. The agent process is called ssh-agent; see that page to see how to run it.

How do I find my ssh-agent key?

Checking for existing SSH keys

1. Open Terminal .
2. Enter ls -al ~/.ssh to see if existing SSH keys are present: $ ls -al ~/.ssh # Lists the files in your .ssh directory, if they exist.
3. Check the directory listing to see if you already have a public SSH key.

How to enable the GPG subkey when using SSH?

Enable the GPG subkey When you use SSH, a program called ssh-agent is used to manage the keys. To use a GPG key, you’ll use a similar program, gpg-agent, that manages GPG keys. To get gpg-agent to handle requests from SSH, you need to enable support by adding the line enable-ssh-support to the ~/.gnupg/gpg-agent.conf.

How to check if SSH key authentication is not working?

This change makes sshd look in a different file based on the username. Verify that the public key authentication is not working via ssh -vvv @hostname and then verify the /etc/ssh/sshd_config file on the host being accessed.

Why does Git sign with GPG keys rather than using SSH keys?

But you can use an ssh key-pair be used with PGP/GPG. So, “Why does git sign with GPG keys rather than using SSH keys?”: it is what GPG is meant to do, as opposed to SSH, which cannot do with openssh alone (it needs openssl). As commented by torek, using SSH would be theoretically possible, it’s just not convenient.

Why do you not use SSH for signing commits?

The reason why you should NOT use ssh for signing commits is the one of the common rules of cryptography: You should not use the same keys for different applications/use cases. In SSH you use a key for authentication, but that is something different then the signing your commits.
