public class Base64InputStream
extends java.io.FilterInputStream
From RFC 2045, section 6.8:
The Base64 Content-Transfer-Encoding is designed to represent arbitrary sequences of octets in a form that need not be humanly readable. The encoding and decoding algorithms are simple, but the encoded data are consistently only about 33 percent larger than the unencoded data.
