located. You may use any character, including spaces, but the ZyXEL Device
drops trailing spaces.
Key Length Select a number from the drop-down list box to determine how many bits the
key should use (512 to 2048). The longer the key, the more secure it is. A

down list boxes and enter the certification authority’s server address. You also
