public class HexCodec extends Codec
[0x01, 0x23, 0xEF] is encoded as the
string "0123EF").
When converting to a string, you may add an optional separator every N
characters (which must be even). This is normally used to create line
breaks, but may be anything: you can create a comma-delimited list with
the separator "\",\"" (although you'll have to prepend and
append the opening and closing quotes).
Conversion to byte arrays always ignores whitespace, and also ignores the
specified separator (if one exists). Any other characters throw an
IllegalArgumentException.
Conversion to byte arrays also ignores any trailing nibble: only an even number of characters will be processed.
