 In this mode of operation, the agent does not only implement the
 gpg-agent protocol, but also the agent protocol used by OpenSSH

+SSH keys, which are to be used through the agent, need to be added to
 the gpg-agent initially through the ssh-add utility.  When a key is
 added, ssh-add will ask for the password of the provided key file and
 send the unprotected key material to the agent; this causes the
