Crc Values
I know theres a way to get crc values using the very handy Crc Calc,, is there anyway or prog that can reverse-engineer the information? (put crc value back into standard format)
There is no way to reverse-engineer the values, but there are ways to find out what a CRC refers to.
I'm not that familiar with the CRC routine used in FL, but all hashing techniques are based on the idea of taking information and producing a short "hash" that represents it. You've actually "lost" information if you have only the hash for a string and not the string itself. The hash is used more or less as an index to look up the detailed value.
The way to handle this problem is to generate CRCs for all of the strings that you're working with and save them with the string. Then you can "look up" the string from the CRC value, which is essentially what the computer typically does with it. The sticky bit here is that the CRCCalc tool isn't designed for bulk crc generation - the GUI obviously requires you to enter each string directly, and you can't even copy the resulting numeric values to put in a lookup file.
