Changing the default rsa key in Git bash for heroku

gistfile1.txt

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

Here's an example of a Git config 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).

Host heroku.com
    Hostname heroku.com
    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 (without .pub)
