How do I SSH with a key?

Public key authentication works like this:

1. Generate a key pair.
2. Give someone (or a server) the public key.
3. Later, anytime you want to authenticate, the person (or the server) asks you to prove you have the private key that corresponds to the public key.
4. You prove you have the private key.

Can public SSH keys share?

Conceivably, you can share the public key with anyone without compromising the private key; you store it on the remote system in a . ssh/authorized_keys directory. To use SSH public key authentication: The remote system must have a version of SSH installed.

How SSH public key looks like?

An SSH key is an alternate way to identify yourself that doesn't require you to enter you username and password every time. SSH keys come in pairs, a public key that gets shared with services like GitHub, and a private key that is stored only on your computer. If the keys match, you're granted access.

What type of SSH key should I use?

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. RSA keys are generally preferred and are the default key type.

How does SSH public private key work?

The most common means of authentication is via SSH asymmetric key pairs. The server uses the public key to encrypt a message and send it to the client. If the client has the correct private key, they can decrypt the message and send it back to the server for verification.

What is SSH key used for?

Essentially, SSH keys are an authentication method used to gain access to an encrypted connection between systems and then ultimately use that connection to manage the remote system.
