Each machine keeps its own copy of these.

· known_hosts.old Exclude
· authorized_keys Exclude
· id_* Never synced
· *.pem Never synced

Only what the catalog names. A directory that syncs brings everything inside it except what is listed as excluded here.

Use it with your dotfile manager

Same data, in the shape your tool already reads
Opens Otty and adds this tool to what it syncs

Opens otty://sync/add/ssh. Otty ships with this catalog, so the link only has to name the tool — nothing is downloaded.

Every one of these keeps all credential files out. None of them splits IdentityFile and IdentityAgent for you — that part is Otty’s own sync, or a template you write by hand.
