SSH Public Key Authentication on Linux
- https://linuxhint.com/ssh-public-key-authentication-on-linux/
- To begin, you need to generate public and private keys. Private and public keys are generated simultaneously by the same device, and then shared with devices you want to allow connections between. In this example, we will generate authentication keys from a client using the ssh-keygen command, and then we will send the public key to the server to allow connections between them. To generate the keys, you need to login as the user allowed to connect. In this tutorial, the user created both in server and client is linuxhint. After executing the ssh-keygen command, the process will ask you in which file you want to save the key, press ENTER to leave the default location (~/.ssh/id_rsa). You also will be asked for a passphrase to encrypt your key. This is recommended but most key authenticated devices don’t use it. You can type a passphrase and press ENTER, or you can just press ENTER, leaving the field empty to avoid encrypting your key. To generate both public and private keys, run the...
