	Game differentiates between a map having a digest or not for online map listing. It's used to ensure all clients (i.e. players) have the same version of the map. If there's a mismatch in the digest value or the map hash/sizes between the players, the game assumes the maps to be different and it will transfer the host's map file to the other players. This section has no effect on singleplayer mission maps.		Game differentiates between a map having a digest or not for online map listing.

			Game's method of generating digest entry is by using the hash of the data from INIClass (internal INI content which doesn't contain comments with some space and tabs removed) and then encoding with base64.

	FinalSun/FinalAlert2 uses system up time as seed for generating a random number which is further processed to make it a 20-bytes long value. Basically, a random number could be used to generate a 20-byte long unique hex value which can be encoded using base64 to generate the unique identification for the map's digest entry. FinalSun/FinalAlert2 doesn't change the digest entry when saving edited maps. It generates a new entry if digest is not present.
