*
* 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.
