When the above '''Old Key Generation''' field is 0x2 on >= v3.0, different {crypto/keydata} is used for the sections' data. With system content, this is used with every ncatype except ncatype0. The only other exception is {data-content} for the firm titles: this is required in order for older-system-versions to install it. | When the above '''Old Key Generation''' field is 0x2 on >= v3.0, different {crypto/keydata} is used for the sections' data.
