what is ssh key

Principle:Key authentication needs to rely on the key, first create a pair of keys (including the public key and the key, and the public key encrypted data can only be decrypted with the key), and put the public key to the need for a remote server.

I didn't care much about using SSH before. After the installation is not how to configure. Login is also directly with the password. This is not too safe, in fact, it is more troublesome, because each time you have to enter a password. If the public

When we use a Linux host, we typically produce two forms of key, one that is generated on a Linux host and then distributed with the private key, and one that is generated with the SSH tool and then uploads the public key to the server. The
