Why have two methods of decrypting for data and normal titles?
|

|

Normal titles can be massive (16mb)! Decrpyting and calculating SHA1 multiple times to test keys
|
||||
is painfully slow. We can quickly test the SRL header for the TID to make sure the key works.
|
||||
|
||||
Data titles can't be tested the same way. Since they're just data, they don't have a header to read.
|

Luckily they tend to be small (10-300kb) so completely decrypting and checking a SHA1 hash is fast.
