Hacking NSP file viewer (to verify complete) in Windows?

[877]

Does any such software exist to browse nsp files in Windows 10?
To avoid copy the large files over to the sdcard and trying to install

I'm sorry, what exactly are you asking? An NSP Verifier? A tool to move large amounts of files?

Hi @Draxzelex

Yes a NSP verifier. The nsp files would be stored on Windows 10 hdd.

I’m pretty sure one doesn’t exist yet.

Lol

Wtf
To verify it just copy it to your switch and install it

CaithSith2 is working on a NSP verify tool which scans all your NSPs and verifies the checksum. If any are corrupt it will output that text and you can redownload them. The tool works, but still undergoing testing he should release it within the week. Just a note ANY files ripped w/ SD to NSP are already verified so they do not need to be verified again. This is only for downloaded NSPs from web or CDNSP.

There is any repository to download and build the tool? First I've heard of a NSP verifier tool and I'm interested in using one.
Corrupted NCA being packaged by Doge or BOB GUI gave me some redownloads and wasted time copying nsp back and forth.

 

[tubebar]

Yes that's why he made the tool as BOB GUI gave me correct NSPs, I had found 6 when I scanned. The tool isn't public yet and I can't release it. CaithSith2 will release it when he is ready to and I am sure he will release the source on github as well. Best to ask him, I am just the a tester.

Yes lol WTF indeed, just one of your many helpful comments

Sounds ideal for downloaded nsp content, will be interesting to see how it develops.
To clarify, I know this is not essential but it will be a useful time saver, especially for those with a large library.

 

[tubebar]

It is essential as BOB and Dodge blindly pack corrupt NSPs. No one wants corrupt data. Granted in my test I only got 6 corrupt out of 1700 so not a high risk.

The tool does not and will never look for the stupid BBB generated meta data files as those are generated from the NCAs and use only for Nintendo developers and submission process. We are not doing that and BBB crap should be dropped by the scene.

 

[PSXDupe]

@tubebar is CaithSith2 a member on here, don't recognise the handle. Do you know where the tool will be release as it would be a huge time save indeed.

For now, google around for the checksums for the nsp files you have downloaded, and then use any program, such like quickhash, to verify the checksums match. If they match then your file is verified.

there are websites with nsp/nca/xci checksum info ?
just tried a google search and nothing came concluding. when caitsith2 tool is released and files verified, maybe proper checksum could be found on a database website. for now, a list of checksum without proper way to verify the file is maybe not trustworthy (unless try tried to install it first)

wouldn't files have different checksum based on who dumped it? which cert/key/ticket used?

try https://github.com/garoxas/NSP-Verifier

can't guarantee it's working though, just something I did in about 30 minutes

 

[PSXDupe]

@Garou Am I correct in saying that you sode only checks the structure of the NSP, eg, #File, File Locations etc, it doesn't do anything to check the contents.

I know very little on this matter, but cant he NCA file etc be check with checksum stored within it.

https://github.com/Rikikooo/pyswitch/blob/master/Examples/verify_nsp.py
Something a little more advanced that uses a lib I've been working on.

 

[Cyan]

Garou, I love your description FAQ (nice cameo) lol
thanks for the tools both of you
from none, we will get 3 at once!

garou: there's no checksum or calculated data possible with nsp file? it's only checking parts length? it's a quick check, that's fine too.

I see rikikoo is doing the sha256 check, but I'm trying to find how to launch it, due to all the module dependencies.
I need to put all the "example" content into the parent folder? and I see I need the key files too.

 

[PSXDupe]

@Rikkoo How do we use your tool, not good with Python at all. But I've tried putting all the examples in the parent folder with the remain .py files but getting a lot of errors with I try to run the verify .py

--------------------- MERGED ---------------------------

I getting the following error, am I missing some crypto module ?


Traceback (most recent call last):

Sounds like you need the Crypto module (run "pip install pycryptodome" in cmd (add "py -m" if you didn't install Python to PATH). On top of my head, it's the only module you'll need to download.

Seem to have got that working, but nows its looking for key files.

Use the CRC32 hashes from http://nswdb.com/ for known releases. If you're building files yourselves, the hash may change depending on your the cert you use. Unsure. But if your files are from BBB or other scene/p2p groups, hashes are on that site. It may help, a little.
