Certainly. You can use the bitAnd/bitOr/bitNot/bitXor to do the work,
and the charToNum/numToChar and binaryEncode/binaryDecode functions to
generate the data or convert it to forms suitable for putting into
fields. Null bytes in variables or custom properties are no problem,
just don't try to put them into fields.
