    You're not limited to these options. You can configure `ssh` to use other ciphers, host key algorithms, and so on. Some other relevant security options you may want to consider are `PermitRootLogin`, `PasswordAuthentication`, and `PermitEmptyPasswords`. For more information, see the `man` page for `sshd_config` or the article [SSH Server Configuration](https://www.ssh.com/ssh/sshd_config).

    ```cmd
-   ssh-keygen -t rsa -b 4096 -m PEM
+   ssh-keygen -t ecdsa -m PEM
    ```
 
-   The command creates a public key and a private key. By default, the keys are saved to *`%USERPROFILE%\.ssh\id_rsa`* and *`%USERPROFILE%\\.ssh\\id_rsa.pub`*. (In PowerShell, use `$env:USERPROFILE` instead of the cmd macro `%USERPROFILE%`) If you change the key name, use the changed name in the steps that follow. We recommend you use a passphrase for increased security.

 1. From Windows, copy the public key to the Linux machine:
 
    ```cmd
-   scp %USERPROFILE%\.ssh\id_rsa.pub user@hostname:
+   scp %USERPROFILE%\.ssh\id_ecdsa.pub user@hostname:
    ```
 
 1. On the Linux system, add the key to the list of authorized keys, and ensure the file has the correct permissions:
 
    ```bash
-   cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
+   cat ~/id_ecdsa.pub >> ~/.ssh/authorized_keys
    chmod 600 ~/.ssh/authorized_keys
    ```
 
 1. Now, you can test to see if the new key works in `ssh`. Use it to sign in from Windows:
 
     ```cmd
-    ssh -i %USERPROFILE%\.ssh\id_rsa user@hostname
+    ssh -i %USERPROFILE%\.ssh\id_ecdsa user@hostname
