Hacking RELEASE NSScreenshotMaker

[cheuble]

NSScreenshotMaker​

NSScreenshotMaker is a tool that will allow you to sign images for the Nintendo Switch. The Switch has an album function to view your screenshots, but it can't read images you put yourself on the SD card.
This tool's purpose is to sign any image so the Switch can read it. I don't really see any use for it, but eh, some people want it ¯\_(ツ)_/¯

Requirements

• The Nintendo Switch capsrv screenshot HMAC secret key
• Python3
• PIL
• piexif
• A FAT32 formatted SD card (ExFat doesn't work at the moment)

You might otherwise use the exe file which doesn't need those requirements (except for the key and the SD card). Your antivirus may block it though.

Usage

• Find the "Nintendo Switch capsrv screenshot HMAC secret" key (Can't share it here for legal reasons). Either save it in a key.bin file (A .bin file is a binary file, so don't use a text editor, use a hex editor like HxD), or pass it as an argument when running the program.
• Create an "input" folder, and put your images in it. Images can be all sizes and formats that PIL supports.
• Download the program and run it. It should output an "SD" folder. Extract its content to the root of your Switch's SD card.

History

• 1.0.2
  
  • Added optional arguments for input and output folders
  • Added verification for the key
  • Fixed a bug regarding the "Archive bit" for some users on Windows

• 1.0.1
  
  • Fixed a bug regarding thumbnails being too large
• 1.0.0
  
  • Initial release

Thanks

• SciresM for documenting how the Screenshot verification works on switchbrew, and for the key.
• s0r00t for testing

Been wanting this thanks

Can read images -> can read corrupted images -> can hack. Muhahahaha.

SciresM already discounted that.

I just meant screenshot editing isn't a huge deal in terms of hax-noteworthiness

Great job! Although relatively useless, I am sure this can be used for exploits in the future!

OMG Thank you so much! I've been waiting this since i bought the console!

...How do I get this "HMAC" key? Do I dump it myself? Search the internet?

...what is it ._.

Also, this is cool. I've wanted to put things in my album for a while...

You can find it on SciresM's pastebin. I can't link here so you'll have to Google it.

any specific resolution? i tried a few images but only 3 show on the album and none displays...

 

[Mnecraft368]

Make this for videos and I can finally download an entire of series of anime, through pirated legit methods, and watch it on my switch

I quickly made a 720p image (resolution of switch images) and I am about to test it. Will tell you if it works.

 

[YTElias]

actually cool now people can watch anime on the go

Seems weird, the resolution shouldn't matter, but try with 1280x720.

The video thing isn't documented yet so I can't atm :/

 

[Mnecraft368]

Works fine.
I reccomend using something like gimp to make a 1280x720 image and put another image ontop of it to make it appear.

Would be funny if this enabled a ChickHEN type exploit further down the line

OP didn't state if it was something we search for online or dump ourselves...but yeah that should've been my first instinct lol

No worries haha, I was going to write out a long math riddle for you to solve to get the key, but I gave up once I got to digit 20

Seems that if the image is too large it wont be able to convert it.
No HD images for us D:

Nothing Gimp cant fix though
