IOException - if an I/O error occurs

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

Writes the given byte array to the output stream in an encoded form.

Parameters:

b - the data to be written

off - the start offset of the data

len - the length of the data

Throws:

IOException - if an I/O error occurs

close

public void close()
           throws IOException

Closes the stream, this MUST be called to ensure proper padding is written to the end of the output stream.

IOException - if an I/O error occurs

encode

public static String encode(String unencoded)

Returns the encoded form of the given unencoded string.

Parameters:

unencoded - the string to encode

Returns:

the encoded form of the unencoded string
