I have lots of different ssh keys, and don&#x27;t share them among different client devices. I do share them across different services, but it turns into N*M anyway because I haven&#x27;t figured out a good way to upload a generated public key from a client device once and have that flow across to all the ssh-compatible services I use. It seems like there should be something for this, but what tool could e.g. speak to both EC2 and GitHub?
