I want to know differences between encTitlekey and decTitlekey. In particular, I've experienced that, with CIAngel, you can download software through ninty servers by using a titleid/enctitlekey pair. However, on that titlekey site, you could add a title key by providing titleid and dectitlekey (not dectitlekey). In fact, on that site, there are some softwares which have only a dectitlekey and not an encrypted one. As far as I can tell, freeshop/CIAngel don't download anything using a dectitlekey but they use encrypted titlekeys, so in my vision the decrypted key upload in the titlekey site is pretty useless. I tried to search for the reason why both seems to be important, but I can't find anything useful. In short, my questions are: 1) What is the relation between encTitlekey and decTitlekey? 2) Since CIAngel and freeShop uses titleID and encTitlekey, why the decTitlekey is important? (seems that is even more important than the encrypted one on that titlekey site) 3) Is it possible to have CIAngel use the encTitlekey instead of the decTitlekey? 4) Is there a way to convert encrypted titlekeys to decrypted titlekeys and/or viceversa? Thank you for the attention, I hope I'll understand more clearly this question.
