Hello,ust Wondering why i need the keys.txt to convert XCI to nsp with 4NWCI. There is some crypto as i heard but the xci I have 2 switchs . does it mean it won't work on the second one ? and if i can convert them to NSP are these NSP specific to my first switch ?
Yes you'll need to convert it for each Switch with each keys seperately. Why? Life's not fair that's why.
games are encrypted using masterkey and these keys are same for every switch systems, so that means your converted nsp will work just fine on another switch
the reason why not just put the keys in the app itself so users don't need to provide their own (as they're the same keys) is because the keys are copyrighted by nintendo so it would be illegal to distribute an app with keys in it

That's right it just needs keys from a Switch not each Switch. Should have known that since there are nsps you can download on pirate sites that don't need keys.
not really sure but I think it's a symmetric encryption (AES) instead of public/private key (asymmetric)
Then why does XCI decryption doesn't work on 6.2 if you have the keys. and 4NWCI works on windows it should not be a probleme. Does it means backups xci done with 6.2 are not unencryptable. and if so how to tell which version of the firemware the xci was done with. Sorry a lot of question in my mind.
FW 6.2 use a new masterkey, please check your keys.txt if you master_key_06 key in it

you need to check the masterkey info instead of firmware info
