How to generate SSH keys

How to Generate SSH Keys on Linux, macOS, and Windows

Generate an SSH Key

Follow these steps to create an SSH key on your local machine. If you already have an SSH key, skip to Add Your SSH Key.

Linux & macOS

1. Open Terminal.

2. Run the command below, replacing your email:

   ssh-keygen -t ed25519 -C "[email protected]"

   This creates a new SSH key with your email as a label.

3. When prompted to enter a file location, press Enter to use the default path. If an existing key is detected, you can create a custom-named key instead.

4. Set a secure passphrase when prompted.

Adding Your SSH Key to the ssh-agent (optional)

ssh-agent is a built-in program in Linux and macOS. It is a background process that manages SSH keys and their passphrases, so you don't have to enter the passphrase every time you use SSH.

1. Start the ssh-agent:

   eval "$(ssh-agent -s)"

2. If using macOS 10.12.2 or later, update your ~/.ssh/config file:

   touch ~/.ssh/config  
   nano ~/.ssh/config  

   Add the following:

   Host *.zeupiter.com
   AddKeysToAgent yes  
   UseKeychain yes  
   IdentityFile ~/.ssh/id_ed25519  

3. Add your private key to the ssh-agent:

   ssh-add --apple-use-keychain ~/.ssh/id_ed25519

Windows

To generate an SSH key on Windows, use PuTTY. Refer to Windows with PuTTY for detailed instructions.
