 *
 * Base encoding of data is used in many situations to store or transfer data in
 * environments that, perhaps for legacy reasons, are restricted to US-ASCII
 * data. Base64 encoding can also be used in new applications that do not have
 * legacy restrictions, simply because it makes it possible to manipulate objects
 * with text editors.
 *
 * In the past, different applications have had different requirements and thus
 * sometimes implemented base encodings in slightly different ways. Today,
 * protocol specifications sometimes use base encodings in general, and "base64"
 * in particular, without a precise description or reference.  Multipurpose
 * Internet Mail Extensions (MIME) is often used as a reference for base64
 * without considering the consequences for line-wrapping or non-alphabet
 * characters.
