Create Public SSH Key

1. Open Git Bash
2. Paste the text below, replacing the email used in the example with your GitHub email address.

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

If you are using a legacy system that doesn't support the Ed25519 algorithm, use:

ssh-keygen -t rsa -b 4096 -C "[email protected]"

This creates a new SSH key, using the provided email as a label.

When you're prompted to "Enter a file in which to save the key", you can press Enter to accept the default file location. Please note that if you created SSH keys previously, ssh-keygen may ask you to rewrite another key, in which case we recommend creating a custom-named SSH key. To do so, type the default file location and replace id_ALGORITHM with your custom key name.

3. At the prompt, type a secure passphrase.

Generating public/private ed25519 key pair.
Enter file in which to save the key (/c/Users/<user>/.ssh/id_ed25519):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/<user>/.ssh/id_ed25519
Your public key has been saved in /c/Users/<user>/.ssh/id_ed25519.pub
The key fingerprint is:
SHA256:<code> <email>
The key's randomart image is:
