+//
+/// The webSafe methods use different character set and also the results aren't
+/// always padded to a multiple of 4 characters.  This is done so the resulting
+/// data can be used in urls and url query arguments without needing any
+/// encoding.  You must use the webSafe* methods together, the data does not
+/// interop with the RFC methods.
