All Implemented Interfaces:
Closeable, AutoCloseable
public class Base64DecodeStream extends InputStream
This class implements a Base64 Character decoder as specified in RFC1113. Unlike some other encoding schemes there is nothing in this encoding that tells the decoder where a buffer starts or stops, so to use it you will need to isolate your encoded data into a single chunk and then feed them this decoder. The simplest way to do that is to read all of the encoded data into a string and then use: 
 byte data[];
 InputStream is = new ByteArrayInputStream(data);
 is = new Base64DecodeStream(is);
On errors, this class throws a IOException with the following detail strings: 
    "Base64DecodeStream: Bad Padding byte (2)."
    "Base64DecodeStream: Bad Padding byte (1)."
