Each valid key line has the following format:
<key identity><white space><256-bit hexadecimal key>, as shown in Figure 5.
The key identity is an alphanumeric name that is used to identify the keys (similar to
the key file entry). The key is also the text displayed when the Show entered keys
button is turned off (Figure 6). It is displayed together with the full key when Show
entered keys is turned on (Figure 7).
You can save the keys in the pull-down list to a .key file. You must click the
corresponding Save button to save a key and to display the standard File dialog box.
All keys in the pull-down list are saved to the selected or created .key file (Figure 4).
