I want to save an SSH key passphrase in gnome-keyring and then use it automatically when I need it.

How to do this?

To save the passphrase, use seahorse-ssh-askpass from package seahorse:

cd $HOME/.ssh /usr/lib/seahorse/seahorse-ssh-askpass my_key

Make sure that the public key is the filename of the private key plus .pub, in the example my_key.pub

To automatically use the key afterwards, see "Gnome Keyring dialog and SSH" and at first use, check "Automatically unlock this key whenever I'm logged in".

    I used this command successfully with Ubuntu 10.04, it seems like it was not even required in Ubuntu 12.04, but with Ubuntu 14.04 I can't seem to be able to store my ssh key password. seahorse-ssh-askpass just prints the password I enter to stdout!!! – asoundmove Mar 20 '17 at 11:52
  • @asoundmove: I had the same experience on 16.04. You can use the seahorse prompt utility via ssh-add, however: SSH_ASKPASS=/usr/lib/seahorse/seahorse-ssh-askpass ssh-add /path/to/private/key </dev/null. Redirecting standard input is required to force the use of SSH_ASKPASS (graphical prompt). – zackse Nov 12 '18 at 22:26

If gnome-keyring-daemon is already running, you can use ssh-add to add your key to the service:

ssh-add /path/to/private/key

For example:

ssh-add ~/.ssh/id_rsa
