   Changes the passphrase that protects the private key. Note that
   this command will work even if the original key is not password
   protected. If the -file argument is not given, the default location
   of the file containing the private key is assumed:

     -- The location pointed to by X509_USER_KEY
     -- If X509_USER_KEY not set, $HOME/.globus/userkey.pem

   Options
      -help, -usage    Displays usage
      -version         Displays version
      -file location   Change passphrase on key stored in the file at
                       the non-standard location 'location'.
