  1. Open pub key file
  2. You CAN use this however you need to do the following:
  3. Chop off the first and last lines.
  4. Take the part of the comment between the double quotes and put it after the double equals at the end. Make sure there is a space AFTER the last ‘=’. Do not quote the comment.
  5. remove all newlines after each line.
  6. Add “ssh-rsa ” to the beginning.
