Let’s check the public key generated with the above command. It is copied to the $HOME/.ssh/authorized_keys file of the remote server. You can simply copy the public key to the remote server for the user to login with the SSH authentication. When you execute the above command, you can get the output as:īoth the public key i.e id_dsa.pub and private key i.e id_dsa are also saved in the default location that is $HOME/.ssh/. For further details, you can execute the command as shown below. But to generate DSA keys, simply put -t dsa as an argument in the command. By default, if you just use the ssh-keygen command, it generates the rsa keys. Likewise, DSA keys can also be created with simple change in the command. Simply copy this public key and paste it to this location: $HOME/.ssh/authorized_keys file of the remote server for the authenticaton. Here, both the public key i.e id_rsa.pub and private key i.e id_rsa are saved in the default location that is $HOME/.ssh/.Īs the public key needs to be copied to the remote server so the user can login with the SSH authentication. $ ssh-keygen -t rsaĪfter executing the above command, you will see the similar output as below. Let’s generate the rsa keys by executing the command as shown below. ![]() Here, ssh-keygen is used to create RSA keys for authentication.
