Hacking Nca signature failed

[MasterZoilus]

Hi,

I use tinfoil 0.2.1.the nsp works fine on 7.01 with atmo 0.8.5.
The problem is i got a message"nca signature verification failed".i install the nsp by usb.
1)I would like to know if it's the version on tinfoil or a problem about my keys?
2)Or just because i converted a xci to nsp which has no ticket?
I used goldeaf 0.5 by usb,the problem is it crash when i quit and the transfert using tinfoil 0.21 is 37 mb/s and goldeaf 18 mb/s but no message about nca just crash.
I would like to stay on 7.01 to use the dejavu exploit


Thanks

1. completely delete the old tinfoil from your system

2. install latest tinfoil (not lithium) from here (what I'm going to show you works perfectly on 7.0.1):
http://tinfoil.io/

3. unzip this file take the folder that is in the Atmosphere folder and put it into the Atmosphere folder that is on your sd card:
shorturl.at/abewx

4. After all that, watch my video, you can go to like the 5:00 minute mark and watch from there thats it! enjoy:

means the NSP has been modified, and it not legit.

yes and no. The nsp has been modded BUT it doesn't mean its NOT legit because if you have made an XCI back up of a cart and convert it to nsp SOMETIMES
the converted nsp will kick up the nca failure but not always. The nsp is legit because you actually made a totally legit xci off of a physical cart that you are holding in your
hand and it will still kick up the error. Obviously the nsp is legit because the xci came off of a physical cart that's YOURS but once in a while the conversion process will make it not seem legit. I've made over 30 xci backups from actual carts that I am physically holding and after converting to nsp the nca fail may still come up because you've removed 0 data files / data zero files / dummy files / padded files or whatever people want to call them.

XCI to NSP conversions are always junk and will fail nca verification.

That is the most oblivious uneducated ignorant noob comment I've ever seen regarding XCI to NSP file conversion. I've done over 80 and none have failed, whenever they have kicked up the NCA error I've just done the steps I mentioned above and they've always worked. Not once have they not. Try educating yourself before spewing nonsense, I know that requires brainmeat so maybe you'll have to go rent some since your space is vacant.

I never said XCI conversions will not install and play, I said they are not legit, which is true. They are no longer signed and verified by Nintendo. Once you modify a NCA in any way, it fails nintendo's signature check, and is no longer legit.

You are confused, the files can be named anything as long as they end with .nsp, you just have to browse for them in the file browser. They wont show up under new games, etc because they cant be indexed unless named properly. But goldleaf doesnt index the files anyway so nothing lost there.

Personally, I think its less complex to set your NSP folder once, that have to pick a NSP file every time you want to install.

That that confusion is widespread is kind of my point. I’ll give you a more detailed critique when I get some time to take a bunch of screenshots and stuff.

For your use case, it is. For the mainstream use, it’s not. Select file on PC, confirm install on switch by hitting A, done. That’s easier.

I get that you have a big library and a certain way you like things to be, but the other way is the default way, it’s what most people expect and if you want XCI conversions to go away, it’s how things have to be.

Thank a lot for your help.masterzoilus i have already watch your video and thanks for you help.
But as blawar said, tinfoil 1.55 can install xci on atmosphere.now i needn't to convert xci to nsp.my last question xci is safe?so no risk to brick my switch?

Tinfoil 1.55 verifies XCI's before installing them, so as long as you do not disable nca verification, you are safe.

Blawar thank youuuu.sorry for my bad english.thanks guys!!
This is the reason i love this site.

I never said XCI conversions will not install and play, I said they are not legit, which is true. They are no longer signed and verified by Nintendo. Once you modify a NCA in any way, it fails nintendo's signature check, and is no longer legit.

Here's where your confusion is coming in, tinfoil dev's put in the nca failure message to prevent people from installing an nsp that has been maliciously modded. When they realized that people with legit XCI's were converting them to nsp's to save space, they put a bypass because to them it meant the nsp is legit....legit meaning it came from you or a reliable source , their definition of legit means its not an nsp that can brick your system. And that is my definition of legit, not whether or not it passes nintendo's checks ...because doesn't nintendo see ALL XCI's and ALL NSP's as not legit!!?? lol thats a given, nothing new there.

My definition of legit is the same as the dev's of tinfoil, especially since most people go around looking for them online... and that is that a GOOD nsp is a legit working and non maliciously modded nsp that will NOT brick your system as opposed to a non legit one that can ruin your system. By default the devs and everybody knows xci's and nsp's are not "legit" and or approved by nintendo.

And not all xci to nsp conversions mess with the nca's to the point of triggering a fail.

yes it can install xci now BUT many times xci take up more space sometimes alot more. I've seen 14GB xci file go down to like 7 or 8GB because the un-needed padded files or junk files ...whatever people call them , get removed. so nsp's can save lots of space.

 

[Gordifas]

Thanks masterzoilus,
But i prefer less space and more safe.
If tinfoil can verify xci and install correctly without risk,i prefer xci.
I prefer without risk.thanks again.and thanks all guys who helped me

 

[blahblah]

And not all xci to nsp conversions mess with the NCAs.

Wrong.

 

[MasterZoilus]

Wrong.

I like how people say wrong but never bother to explain why! So explain .....and explain in developer terms so you can educate everybody.
Explain why I like everybody else can convert get an xci straight from a cart and sometimes the nca error is triggered and why sometimes
its not. I'm not talking about random xci's and nsp found online , I'm talking about a direct 1 for 1 xci that you yourself made directly from a
cart. Because according to you ALL converted nsp's have changed the nca's enough to trigger the nca fail notification and that is NOT the case.

I can make a video showing me ripping at least 3 random carts.. I'll even let you pick which 3 and you'll see in real time the nca fail will not be triggered
for all 3 after converting. maybe for one, maybe, but not all 3.

so explain why you say you're right ....instead of saying something stupid like "wrong" without providing zero proof . typical millennial

lol if the xci is safe, YOU convert it to nsp. the nsp is coming from a working xci so it will be safe. NSP's are NOT safe when you just download random ones from somewhere.
Converting a good working xci to nsp yourself does NOT make it not safe.

 

[satel]

Wow you are the best.thank youuu.now i don't know why i converted xci to nsp.i didn't know.i just install xci on atmosphere using tinfoil 1.55.

Thank a lot

can you install xci's via usb or only via sd ?

 

[blawar]

can you install xci's via usb or only via sd ?

Should work over USB using USBFS.

I'll try to explain in developer terms, though please correct me if I am wrong.

XCI is just a fancy folder, just like NSP's. The actual program files that are installed or ran, are NCA's. Inside of the NCA, there is a header that has a flag that says whether the NCA is from a XCI, or installable content. XCI to NSP conversion is really just modifying the NCA header to change the type from "XCI" to "NSP", hence all XCI conversions are modified. Nintendo signs all of their NCA's with a private key that only nintendo has, Changing even one byte in the NCA causes this signature to fail, as is the case in changing the one byte in the XCI conversion (it changes others stuff, but we'll stick with the one byte to keep it simple). This is why all XCI conversions fail signature checks.

Every XCI that is dumped from a legit game cart has signed NCA's and will pass validation.

I love that this guy is arguing how XCI conversions work on a technical level with you. It's genuinely hilarious, he's completely outmatched on every level.

Everything you said is wrong, and Blawar's reply is a solid explanation of why.

 

[MasterZoilus]

@blahblah

yeah you keep believing that. but your problem is comprehension. My arguement, if you were paying attention and CLEARLY you were't, you just like having your tongue up blawar's ass, is that an nsp will NOT always kick up an NCA fail. The explanation that @blawar gave while an accurate one and one I already knew still didn't explain what I asked him to explain which was... and had to do with the OP's first post, "why is the nca failure being kicked up on tinfoil" because by your logic, which is actually blawar's not yours,
EVERY conversion from xci to nsp because of the changes to the header should kick up an error every single time in tinfoil... and it does not!

not only that, but that nca fail can actually be bypassed the game, even with the nca warning , will still install and play fine. Instead of just agreeing without proof maybe you should actually try it!

So my whole point is that a conversion from xci to nsp many times , through tinfoil, will NOT kick up an nca error. Technically according to you and your boy it should, every single time and or the game shouldn't be playable which is completely not true. Every single converted xci to nsp i've done has never not installed. Once in a while in tinfoil it will give the nca error but its there because they think that the nsp maybe be a malicious one from online somewhere, but now they've installed a way to bypass it for those who are converting legit xci's .... that's my whole point which answers the OP's actual question and even sheds more light and info on his situation.

The easiest way to do this if you think I don't know what i'm talking about is just to grab a couple or a few game carts. Extract them to xci. convert them to nsp and use tinfoil to try to install, follow my steps I gave to the op , you will see most of the time the nca error does NOT come up , even with the new yoshi game it doesn't. but even if it does come up, its only a warning from TINFOIL not nintendo and that warning can be bypass. game installs. done. So thats the easiest way to test if what i'm saying is bullshit or not .
Then you can STFU when you see everything I said is 100% right.

Cryptography is not a debatable thing. Modifying the NCAs is required to convert an XCI to an NSP, and that breaks the signature. So NCA signature checking will fail. Always. Always, always. Regardless of what you claim.

The rest of what you said ranges from wrong to less than smart.

I am not even going to respond to @MasterZoilus ’s post, there is so much wrong.

I don’t think he even realizes who I am.

The sad part is, i do not think he is trolling. I believe he truly believes the shit in his head.

Agreed, agreed. On all counts.

A question about xci.tinfoil 1.55 can install super xci or just xci?

 

[blawar]

A question about xci.tinfoil 1.55 can install super xci or just xci?

Tinfoil supports multi-content XCI and NSP. it will automatically ignore any patches in XCI's however, since XCI patches are almost always outdated.
