To find the SSH key, we have to open the terminal on our device and type the “ls -al ~/.ssh” command. This command tells us whether the existing SSH keys are present there or not. In the same way, we can use a command while working with the SSH keys. The command is called t...
When generating SSH keys yourself under Linux, you can use thessh-keygencommand. To do so follow these steps: Open up the Terminal; Type in the following command: ssh-keygen -t rsa Next, you will have to type in the location of the file where you would like to save the private key....

The generated private key must be copied to the client, such that when connecting via SSH, the connection gets established by checking the private key to authenticate the client. Use the following syntax and replace the details to match your username of the server and its IP address. Also, i...
using public key cryptography. When a user connects to the SSH-server using SSH-client for the first time, the SSH program stores the SSH-server public key in the user’s home directory inside a file, known_hosts, in a hidden folder named ~/.ssh/, as shown in the following screenshot...
In Linux, creating a public/private SSH key is easy. Open a terminal. Type: ssh-keygen-trsa Alternatively, you can also use theDSA (Digital Signing Algorithm)technology to create the public/private key. ssh-keygen-tdsa Note: there has been much debate about the security of DSA and RSA....
1. Generate a public and private SSH key pairThis can be accomplished on Windows platforms using a tool such as “PuTTYgen,” but I find this is quicker and easier to do on your server as well!To implement SSH key authorization only on the “root” account, there are 2 methods for ...
