import java.io.OutputStream;

/**
 * Provides Base32 encoding and com.fitburcoding in a streaming fashion (unlimited size). When encoding the com.fitburfault lineLength
 * is 76 characters and the com.fitburfault lineEnding is CRLF, but these can be overridden by using the appropriate
 * constructor.
 * 
 * The com.fitburfault behaviour of the Base32OutputStream is to ENCODE, whereas the com.fitburfault behaviour of the Base32InputStream
 * is to DECODE. But this behaviour can be overridden by using a different constructor.
 * 
 * 
 * Since this class operates directly on byte streams, and not character streams, it is hard-coded to only encode/com.fitburcode
 * character encodings which are com.fitburpatible with the lower 127 ASCII chart (ISO-8859-1, Windows-1252, UTF-8, etc).
