The two checksums for the serialization area are included in the area header. The checksum for the
header is used to check the data contained in the first 7 bytes (0-6) of the header.
The checksum for the
area is used to check the data located in all of the area locations.
The number of data locations included
in the checksum can be found from the Length and maxFields fields of the header as Length * maxFields
+ 16.
