Set up GitHub with SSH on iOS

1. Install iSH Shell
   Download iSH Shell from the App Store and open it.
2. Install Git and OpenSSH
   In the terminal, run:

   apk add git openssh
   

3. Set Git username

   git config --global user.name "Your Name"
   

4. Set Git email

   git config --global user.email "your_email@example.com"
   

5. Generate a new SSH key
   Replace the email with your own:

   ssh-keygen -t ed25519 -C "your_email@example.com"
   

6. Start the ssh-agent

   eval "$(ssh-agent -s)"
   

7. Add your SSH private key to the agent

   ssh-add /root/.ssh/id_ed25519
   

8. Copy your public key
   Display your public key and copy the output:

   cat /root/.ssh/id_ed25519.pub
   

9. Add the key to GitHub
   Go to GitHub's "Add new SSH Key" page, give it a title, and paste the public key into the Key field.

Done! Your iOS device is now set up to use Git over SSH. You can clone, push, and pull repositories securely right from your iPhone or iPad.
