This week’s techmail is What you need to know about OpenSSH key management which looks at a few tips and tricks in using OpenSSH public/private keys. It talks about generating keys, using ssh-copy-id to copy keys to servers, and using hashed representations of host keys to obscure what machines you connect to in case someone is able to look at your known_hosts file. If you’re not familiar with OpenSSH or want to move beyond just the simple basics, this tip will help you get started.
