How 3DS system judge encryption type? Matyapiro
Sorry the question is not understood. What do you mean? Neimod
I think that he means "How does the 3DS decide what encryption method must be used" --Quincy 23:47, 29 May 2011 (CEST)
That question does not make sense. There are no decisions. It is always AES CTR. Neimod
Sorry,how does the 3DS decide what key to use for encryption? Matyapiro
- If you figure that out, let us know, thanks. Neimod 02:45, 1 June 2011 (CEST)
There's a common key used to generate output at compile time, when the cci/ctx files are made. Why do you say 128 bit AES CTR though? Jl12
- Because 128-bit AES CTR is used to encrypt those formats. --Neimod 15:40, 18 June 2011 (CEST)
I know *something* is used to encrypt but do we know it is 128 bit AES CTR? Jl12
Frankly I don't think it was AES. I think it's using RSA for encryption. Besides it already used it once for the 2048-bit signature as you said. Wouldn't it make way more sense to also use it for the encryption scheme. Jl12
- Lol. --Neimod 16:06, 20 June 2011 (CEST)
- And what's funny? So I guess it's just based purely on speculation? You should say so. That way nobody believes something that isn't right. Jl12 22:28, 20 June 2011 (CEST)
How did you get this data? Did you find some way to dump 3DS cartridges? --Popoffka 09:15, 1 June 2011 (CEST)
- Yes, someone found a way to dump the data on 3DS cards. Unfortunately the method cannot be disclosed, and at this point dumping is not really useful since most of the information is encrypted. Neimod 10:03, 1 June 2011 (CEST)
- CCI files are 'CTR card images', which are burned to ROM. If the application is ran from NAND then a CXI file is generated instead. CIA files are installed to NAND after they are imported or loaded from a external source first ( the SD card ). CXI are required to make a CIA file.Jl12
I want you to write express about key words when you change the page...
I can understand what you say,but someone visit this wiki first will probably give up,I think...Matyapiro
- CXI == ran from NAND.
- CCI == cart/ROM format.
- CIA == imported from an external source. *Then* executed from NAND. "external source" is either an SD card or (official) debugging hardware.
I'm just explaining there are many analogues to the CXI format and they're all similar to each other but compiled/linked for different purposes mostly. (It isn't a comprehensive list, either. )
