decodeChunk
public static byte[] decodeChunk(char[] id, int o, int l) throws Base64Exception
Thedecode_chunk
routine decodes a chunk of data into its native encoding. base64 encodes each 3 octets of data into 4 characters from a limited 64 character set. The 3 octets are joined to form 24 bits which are then split into 4 x 6bit values. Each 6 bit value is then used as an index into the 64 character table of base64 chars. If the total data length is not a 3 octet multiple the '=' char is used as padding for the final 4 char group, either 1 octet + '==' or 2 octets + '='.- Parameters:
id
- The input data to be processedo
- The offset from which to begin processingl
- The length (bound) at which processing is to end- Returns:
- The decoded data
- Throws:
Base64Exception
- Thrown is processing fails due to formatting exceptions in the encoded data
