  • Once PuTTYgen finishes generating keys it will display the public key and other details in the application window.
  • Enter a passphrase and confirm. (make sure this is SECURE, and noted somewhere for future reference)
  • Click “Save public key” and save the key with a filename (ex: red5pro_node) on your file system in a secure location (or a common standard folder such as ~/.ssh/ under your user profile). Provide an extension of .pub to the file (public key).
  • Click “Save private key” and save the key with the same filename as the public key (ex: red5pro_node) on your file system in a secure location (or a common standard folder such as ~/.ssh/ under your user profile). Provide an extension of .ppk to the file (private key).
