Arun Suresh commented on HADOOP-10937:
--------------------------------------
So the point of setting the versionName as "EEK" is to mark the fact that the
Key has been encrypted.. and the precondition check is to ensure that only
encrypted keys can be decrypted. Essentially, the assumption was that the
KeyProvider would be the only entity that generates the EncryptedKey and it
would decrypt keys generated by it.
