Someone found this file (.plugin extension) , where there is supposedly interesting stuff. Most of the file's contents are encrypted, and I don't know how to decrypt it (the decryption process is probably related to the dev keys, which I have).

Perhaps it'd be better to upload said file and not black out the first 0x10 bytes.

Yeah sorry, someone who wants to stay anon., got this file I-don't-know-where, and had no clue about it either. Thus the "I".

Anyways there were another file that came with it, a .debugger file, containing some function-name-related symbols, such as "update_firmware()", "note_new()", "//DevMenuCTR"

Telling us about said file is not the same as uploading the file for others to tell you what it is.

Looks like it contains some form of bytecode, maybe Lua or something. Edit: Or maybe it's just some encryption throwing me off.

I believe there is too few zeroes for it to be bytecode. Moreover, I think signature-like data is located just after "PROCESS" (compare UiT.plugin with UiT (1).plugin; the encrypted data is EXACTLY the same between the two files, but the signature is totally different due to a modification in the header)

1.The most content of the file should be encrypted. Just try load it into a IDA (you can find 6.6).
2.No those Dev Cert marks such as "CP00000004" or "XS0000000A" is involved. Oh this is only for those NCCHs.
3.There are dev keys leaked very long ago, including AES and RSA types. The amount of those is finite.
4.This file isn't found in NW4C:NW4F, or leaked 4.2.8 SDK.
Since i don't find any clue about where this file comes from, i don't know what it belongs.
You may just want to write a tiny program to try all those keys for you, but this may be not enough.
If you have a dev console, write a program to let it try all its keyslots.
~~Even i do want the SDK to generate new version of libraries' signatures, i won't ask it publicly.~~
Let me guess. If a file is designed to be used inside a system with many keys, it may at least tell the system which key should be used.
Otherwise it could not be decrypted well. I don't know if the 0x31=49 is a slot number.

Good luck. Hope you could eventually play with it.

They have to know where they got the file from. I seriously doubt it just poofed into existence on their hard drive.
