    Default how to recreate a value created by the add checksum step

    I am trying to match a checksum generated by the 'add checksum' step and seem to be having issues when attempting to recreate the checksum by hand.

    In this case it is a combination of 4 columns from each record and so I guess the question is how should I be presenting them to my hashlib/routine? (e.g. as an object, delimited string, list, dictionary??)
    Depending on the answer are they named or indexed? ... all crammed together with one big concat?

    Thanks in advance!

    Have a look at the source code... from memory... all crammed together.

    I believe you want to look at:

    It looks like it separates fields with a hyphen via a call to getString().

    Thanks again for the tips.

    --- begin cut ---
    private static String getString(byte[] bytes) {
    StringBuffer sb = new StringBuffer();
    for (int i = 0; i < bytes.length; i++) {
    byte b = bytes[i];
    sb.append((int) (0x00FF & b));
    if (i + 1 < bytes.length) {
    return sb.toString();
    --- end cut ---
