What is SSH key in Linode?

Last updated on September 25, 2022 @ 1:02 pm

SSH key is a secret key that is used to authenticate a user with a remote server. A SSH key is a string of characters that is used to encrypt a session between a user and a remote server. The SSH key is stored in the user’s ~/.ssh directory on the remote server.

The user’s public key is published on the user’s public key server. The user can use the user’s public key to authenticate themselves with a remote server.

PRO TIP: SSH key is a private key used for authentication. It is recommended that you keep your SSH key confidential and do not share it with anyone.

A SSH key can be used to connect to a remote server using SSH. The user must have a SSH key and the remote server must have a SSH key. The user can create a SSH key using the ssh-keygen command.

The user can copy the public key to the remote server. The user can use the ssh command to connect to the remote server and use the ssh-add command to add the user’s SSH key to the remote server.
