-### Example
+## Setting up a SSH Key
 
-Copy file via ssh password
+Make sure to follow the steps below when creating and using SSH keys.
+The best practice is to create the SSH keys on the local machine, not the remote machine.
+Log in with the username specified in GitHub Secrets and generate an RSA key pair:
+
+```bash
+# rsa
+ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
+
+# ed25519
+ssh-keygen -t ed25519 -a 200 -C "your_email@example.com"
+```
+
+Add newly generated key into Authorized keys. Read more about authorized keys [here](https://www.ssh.com/ssh/authorized_keys/).
+
+```bash
+# rsa
+cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
+
+# d25519
+cat .ssh/id_ed25519.pub | ssh b@B 'cat >> .ssh/authorized_keys'
+```
+
+Copy Private Key content and paste in Github Secrets.
+
+```bash
+# rsa
+clip < ~/.ssh/id_rsa
+
+# ed25519
+clip < ~/.ssh/id_ed25519
+```
+
+See the detail information about [SSH login without password](http://www.linuxproblem.org/art_9.html).
+
+**A note** from one of our readers: Depending on your version of SSH you might also have to do the following changes:
+
+- Put the public key in `.ssh/authorized_keys2`
+- Change the permissions of `.ssh` to 700
+- Change the permissions of `.ssh/authorized_keys2` to 640
+
+### If you are using OpenSSH
+
+If you are currently using OpenSSH and are getting the following error:
+
+```bash
+ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey]
+```
+
+Make sure that your key algorithm of choice is supported.
+On Ubuntu 20.04 or later you must explicitly allow the use of the ssh-rsa algorithm. Add the following line to your OpenSSH daemon file (which is either `/etc/ssh/sshd_config` or a drop-in file under `/etc/ssh/sshd_config.d/`):
+
+```bash
+CASignatureAlgorithms +ssh-rsa
+```
+
+Alternatively, `ed25519` keys are accepted by default in OpenSSH. You could use this instead of rsa if needed:
+
+```bash
+ssh-keygen -t ed25519 -a 200 -C "your_email@example.com"
+```
+

 Protecting a Private Key. The purpose of the passphrase is usually to encrypt the private key. This makes the key file by itself useless to an attacker. It is not uncommon for files to leak from backups or decommissioned hardware, and hackers commonly exfiltrate files from compromised systems.
