Hi there,

I am trying to implement a CRC8 algorithm in Java. I understand the algorithm, but it would save me a lot of time, if I get some implementation hints.
I want to calculate the CRC8 value of a HEX String that is 15 bytes long and store the CRC value in one byte.
I know that there is a utility called jacksum, but I don't want to use it, because I would have to make my application open source (jacksum is GPL).
If you insert a complete algorithm that gets a string data value and a poly as arguments and returns the string crc value, you'll instantly get the 500 points.

Thanks a lot.

checkout this:


        CRC32 crc = new CRC32();
        crc.update(...);
        long hash = crc.getValue()
