+- The length field must contain the size of the data in bytes.
+- The crc32 field must contain the CRC32 checksum of the data.
+- The type_id field must contain the type of the message.
+- All values must be encoded as strings fields with leading zeros.
+- All values in the fields must be treated as unsigned integers.
