public class Base32 extends BaseNCodec
The class can be parameterized in the following manner with various constructors:
This class operates directly on byte streams, and not character streams.
This class is thread-safe.

When encoding the line length is 0 (no chunking).
public Base32(boolean useHex)
When encoding the line length is 0 (no chunking).
useHex - if true then use Base32 Hex alphabetpublic Base32(boolean useHex,
byte pad)
When encoding the line length is 0 (no chunking).
useHex - if true then use Base32 Hex alphabetpad - byte used as padding byte.public Base32(byte pad)
When encoding the line length is 0 (no chunking).
pad - byte used as padding byte.public Base32(int lineLength)
When encoding the line length is given in the constructor, the line separator is CRLF.
lineLength - Each line of encoded data will be at most of the given length (rounded down to nearest multiple of
8). If lineLength <= 0, then the output will not be divided into lines (chunks). Ignored when
decoding.public Base32(int lineLength,
byte[] lineSeparator)
When encoding the line length and line separator are given in the constructor.
Line lengths that aren't multiples of 8 will still essentially end up being multiples of 8 in the encoded data.
lineLength - Each line of encoded data will be at most of the given length (rounded down to nearest multiple of
8). If lineLength <= 0, then the output will not be divided into lines (chunks). Ignored when
decoding.lineSeparator - Each line of encoded data will end with this sequence of bytes.IllegalArgumentException - The provided lineSeparator included some Base32 characters. That's not going to work!public Base32(int lineLength,

octet is in the Base32 alphabet.isInAlphabet in class BaseNCodecoctet - The value to testtrue if the value is defined in the the Base32 alphabet false otherwise.
