         * Title metadata is a format used to store information about a title (a single standalone game, channel, etc.) and all its installed contents, including which contents they consist of and their SHA1 hashes.

Many operations are done in terms of 64-byte blocks, which means you will often see padding out to the nearest 64-byte boundary at the end of a field.
