→Defined Signature IDs
ID 1: The signature type is 2048-bit RSA-PKCS1-SHA1
The updater program will not use a MAR file if one of the known signatures does not verify. If the updater program encounters a Signature ID that it does not know about, it will not check the signature, and will proceed to the next signature. This is why there exists a "4 bytes : length of signature" SignatureLength field, so that unknown signatures can be skipped.
Some versions of the updater may not apply a MAR file unless a specific Signature ID is inside of them.
