Enum KeySource 

pub enum KeySource {
    File(PathBuf, Option<SecretString>),
    Agent(PathBuf),
}

Where the SSH session sources its private key from. The CLI’s resolution stack collapses --ssh-key, profile entries, FERRULE_<NAME>_SSH_KEY, default identity files, and SSH_AUTH_SOCK into one of these variants before reaching setup_tunnel.

Variants

File(PathBuf, Option<SecretString>)

A private key file on disk. The russh layer loads and (if encrypted) decrypts it via russh::keys::load_secret_key. None means probe first and error if encrypted; Some means attempt decryption with the provided passphrase.

Agent(PathBuf)

SSH agent socket. The russh layer routes signing requests through the agent at this socket path.
