Hacking Hacking the Switch through the Album?

[Mnecraft368]

What do you use to sign the image?
I probably sound like a noob

Signing the image requires a hex editor, the secret key (which can be found on SciresM's pastebin page) and a method to generate HMACs from data.

I recommend reading what he wrote here: http://switchbrew.org/index.php?title=Capture_services

Its not enough to hide code in a file, the switch has to be able to execute the code, and without an actual exploit, thats not going to happen.

That site doesn't make any sense to me.
What are HMACs and what do I do with the key?

If that site doesn't make sense you shouldn't be trying this.

You open up the JPEG file that has the EXIF header data from a screenshot from the Switch. Then, you zero out the Maker Notes and generate an HMAC-SHA256 of the entire JPG by using the secret key. Copy that into the maker notes and then you have a working image.

This is assuming that Nintendo didn't include a custom method to generate their own HMAC-SHA256 that can't be replicated without the looking at the capsrv.

If this didn't make sense then you shouldn't even be attempting this.

It's standard; I used python's hashlib in testing.

Oh. Thanks for that info. Now it must be something stupid on my end why I can't get it to work lol.

Well, it might be because I'm on 3.0.

A person could make a batch tool for this.. but ehm it's not like the switch is very comfortable to use during ehh.. the thing..

I think something with the joycon could be more realistic. We have a tool that lets you change the color via hex code. I can see pairing a hacked joycon allowing to launch code from SD happening. Probably not gonna happen for a while though.

I don't see how you go from "can change a 32-bit color value" to "can run arbitrary code". The color adjustment is intentional; it makes it easier to use the same boards for all Joy-Cons without programming the color until the last step.

The color value is read as a value. It isn't executed as code.

That's funny, i swear I made a joke about this somewhere, about it being related to that Chicken hen PSP exploit.
