Are SSH keys server specific?
SSH key pair’s are machine independent, which means you can create a SSH key pair on one machine and can deploy the same SSH key pair on multiple machines. It is valid thing to do, thats how you must do it.
Where are SSH keys stored?
ssh/id_rsa and the public key is stored in ~/. ssh/id_rsa. pub . The private key should only be kept on your local system and should be encrypted using a passphrase that is at least as strong as any password you would normally use.
Can you reuse SSH keys?
Your private key is never sent to the other site so it’s perfectly safe to reuse the public key. It’s also OK to reuse the same key your local computers. However, bear in mind that if someone steals the key, they then have access to all of them.
How does a client know which SSH key to use?
When a client connects to the host, wishing to use SSH key authentication, it will inform the server of this intent and will tell the server which public key to use. The server then checks its authorized_keys file for the public key, generates a random string, and encrypts it using the public key.
What’s the difference between public and private SSH keys?
Each set contains a public and a private key. The public key can be shared freely without concern, while the private key must be vigilantly guarded and never exposed to anyone. To authenticate using SSH keys, a user must have an SSH key pair on their local computer.
How to configure SSH to point to a different directory?
Configure SSH to point to a different directory If you did not save your SSH key pair in the default directory, configure your SSH client to point to the directory where the private key is stored. Open a terminal and run this command: eval $ (ssh-agent -s) ssh-add
How can I authenticate to a remote SSH server?
Generating a new SSH public and private key pair on your local computer is the first step towards authenticating with a remote server without a password. Unless there is a good reason not to, you should always authenticate using SSH keys. A number of cryptographic algorithms can be used to generate SSH keys, including RSA, DSA, and ECDSA.
