search for: identityfingerprint

...e found at the specified path. I have a use case in which keys are added to ssh-agent on a forwarded connection, but are not present on disk locally. There is currently no way to refer to a key in ssh-agent that is not also sitting on local disk. I propose either a new config (which I'm calling IdentityFingerprint) or extending the existing IdentityFile to accept the fingerprint (e.g. output from ssh-add -l: SHA256:...) of a key and use that if it's found in ssh-agent. Is this a reasonable feature? Am I missing a way in which this is already supported? --Greg
