Setting Up SSH Key Authentication in WhaleDeck: A Complete Guide

Do you want to use WhaleDeck-compatible SSH Key? No problem! Follow the instructions for your operating system.

Generate SSH Key

The first step is to generate a compatible SSH key. WhaleDeck supports ED25519 and RSA keys in OPENSSH format.

MacOS & Linux

Run the following command in your Terminal and enter your filename and optional passphrase:

ssh-keygen -t ed25519

In the following example, I generate a key pair named WhaleDeck_Key without a passphrase. The folder, in which I ran the command, contains now two files named WhaleDeck_Key &

The folder, in which you ran the command, contains now two files named WhaleDeck_Key &

Deploy SSH Key

You now need to deploy the generated public key on your server. For that, you need to add the content of your .pub file to your user's authorized_keys.

This can usually be done by running the following command on your server:

echo 'YOUR PUBLIC KEY CONTENT' >> ~/.ssh/authorized_keys

The last step is to restart your SSH server. This either can be archived by restarting your entire server or only your SSH server. DDependingon your used operating system and SSH server, one of the following commands should do the job.

service sshd restart
service ssh restart
sudo systemctl restart sshd

Use SSH Key

Finally, add the SSH key to your server in WhaleDeck. For that, add the content of your private key (the one without .pub) to the key-section and enter your passphrase in the password field if you set one during the creation process.
