How do I tell Git for Windows where to find my private RSA key?

Using the built-in SSH client shipped with Git for Windows, you need to set up the HOME environment variable so that the Git SSH client can find the key.

For example, on a Windows Vista installation, this would be done by issuing setx HOME c:\Users\admin\ on the command line.

It made my day and fixed the issue with Git provided that your private key is not password protected. If you want to use ssh-agent, then you can probably run ssh-agent cmd.exe (although I've never done that) and the ssh-add as usual.

Note that all Git/SSH tools are supposed to be run from a cmd.exe in order not to blink a window.

If this does not work correctly, using plink can probably be achieved by tweaking GIT_SSH. Refer to all the SVN + ssh tutorials; this is basically the same plumbing you need to setup.

If you're using msysgit with the OpenSSH tools, you need to either create ~/.ssh/id_rsa, or create a Git configuration in ~/.ssh/config which points to your key.

Here's an example of a Git configuration for Bitbucket that will use the correct username, and a key other than the default key (in case you maintain one key for SSH connections, and another for Git accounts).

~/.ssh/config:



Host bitbucket.org

    Hostname bitbucket.org

    User git

    IdentityFile /C/keys/yourkey.key

Once in Git Bash, you can run two commands to add your key to your current session's ssh-agent to avoid having to repeatedly type the key's password.

eval `ssh-agent`

ssh-add /C/keys/yourkey.key
