Hacking Question Change nsp certs

[shirogeek]

Hey guys,
Just wanted to know if it was possible to change/inject/extract certs ( headers ) from nsps the same way it is possible with xci file ?
Thanks

I think digital downloads are all the same. The authentication is all done on the server side. Meaning Nintendo don't need certs on it.

NSPs dont have certs

I believe you mean to change headers of games. The cert is in the console.

game carts have their own certs too

NSP do have certs, just unpack them and see. Also digital games have their own certs downloaded when leeching the ticket.
It's not 3DS.

Thanks for the replies, i mean the header identifying the games. I've been injecting my botw cert on a splatoon 2 dump i got from my friend's card. Meant to try the same with nsps cause i haven't been banned ever since. I know there is no guatantee but better than nothing. I don't see how to do that. Xci explorer allows it for xci files and it's called cert over there

Only .XCI files use a certificate/header. .NSP files I believe use their ticket to go online which can only be legitimately obtained by buying that specific game. You also cannot remove a ticket from one game and install it into another as no 2 tickets are identical. I suggest reading up on online play verification here to understand what you are asking for is impossible: https://www.reddit.com/r/SwitchHacks/comments/8rxg26/psa_strong_antipiracy_measures_implemented_by/

there is a way to convert xci to nsp i believe. you could perhaps use the same process and then convert.

It won't convert the certificate into the ticket because they are two completely different formats. Tickets require certain data to be present in order to be forged such as Nintendo Account which cannot be found in the certificate making the conversion process impossible.

EDIT: Forgot to mention the fact that certs are encrypted with Nintendo's personal 2048 character signing key so 4NXCI won't even be able to crack the cert to try to convert it

I understand, thanks for clearing everything up
