    Please use at least 2048. 4096 is recommended.
  • Click "Generate", move the mouse cursor over the blank area until you see your key.
  • Copy the text inside the "Key" text box.
    This is your "public key", which starts with "ssh-rsa".
    Make sure you copy all the text.
  • You can enter "key comment" or "key passphrase".
    If "key passphrase" is specified, using the key requires entering password.
    Click "Save private key" to save a ".ppk" format key.
