example of serials that has been encrypted. in reality we do not know the md5 hash, the serials, and the md5total.
serials:

the md5 hash that we do not know:
cc460b0e0035f80845afb15f8b50dc55
the first md5total
223
with each md5total based off the last one and all the past chars,everything works out
ord('C')+12-223=-144
ord('O')+12-187=-96
ord('N')+4-229=-147 and so on so forth...
