== Defined Signature IDs ==
ID 1: An SHA1 hash signed with RSA 2048, the first certificate shipped with FF Firefox must be used.
The updater program will not use a MAR file if one of the known signed hashes do not verify. If the updater program encounters a Hash ID that it does not know about, it will not verify its hash and proceed onto the next hash. This is why there exists a "4 bytes : length of the hash" field, so that unknown hash IDs can be skipped.
