The IdentityFile config (or -i argument) lets you insist on (or prioritize, at least) a particular key file on disk. The key can be retrieved from ssh-agent without decrypting the file on disk, but it must be 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 _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
