In this window, there are three options to provide a public key for this service instance, by slecting their radio button:
-  Key File Name: Click Choose File and browse and select a file that has a public key. (After you select  a file, the Choose File button changes to an Update button, shown in this image.)
- Key Value: Paste the value of a public key into the given field
- Create a New Key: Have the system generate a pair of public/private keys for you.
The first option, Key File Name, is selected for this tutorial and the file name is displayed as "publicKey". There is an Update button for the Key File Name, in case you want to update the file. Ther Enter button is also highlighted, suggesting that you should click it, after you select your file.
