need function to output entire ssh key for openpgp key
Just as sshfpr outputs to stdout the ssh fingerprint of a openpgp key, it would be nice to have function that outputs to stdout the entire ssh key for a openpgp key. It should also be aware of the issues mentioned in #1436 (closed).
It seems like it might be a good idea to provide a lot of the similar interface as ssh-add. We might think of a good way to unify these features nicely.
