ssh-agent

From RaySoft

ssh-agent is a program to hold private keys used for public key authentication (RSA, DSA, ECDSA, Ed25519). The idea is that ssh-agent is started in the beginning of an X-session or a login session, and all other windows or programs are started as clients to the ssh-agent program. Through use of environment variables the agent can be located and automatically used for authentication when logging in to other machines using ssh.[1]
