<p>Arthur: </p> <hr /> <div>How 3DS system judge encryption type? --[[User_talk:Matyapiro|Matyapiro]]<br /> : Sorry the question is not understood. What do you mean? --[[User:Neimod|Neimod]]<br /> <br /> :: I think that he means &quot;How does the 3DS decide what encryption method must be used&quot; --[[User:Quincy|Quincy]] 23:47, 29 May 2011 (CEST)<br /> <br /> ::: That question does not make sense. There are no decisions. It is always AES CTR. --[[User:Neimod|Neimod]]<br /> <br /> Sorry,how does the 3DS decide what key to use for encryption?<br /> --[[User_talk:Matyapiro|Matyapiro]]<br /> : If you figure that out, let us know, thanks. --[[User:Neimod|Neimod]] 02:45, 1 June 2011 (CEST)<br /> 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? --[[User:Jl12|Jl12]]<br /> : Because 128-bit AES CTR is used to encrypt those formats. --[[User:Neimod|Neimod]] 15:40, 18 June 2011 (CEST)<br /> <br /> I know *something* is used to encrypt but do we know it is 128 bit AES CTR? --[[User:Jl12|Jl12]]<br /> <br /> 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. --[[User:Jl12|Jl12]]<br /> : Lol. --[[User:Neimod|Neimod]] 16:06, 20 June 2011 (CEST)<br /> 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. --[[User:Jl12|Jl12]] 22:28, 20 June 2011 (CEST)<br /> : RSA is only used for the signature. After that a symmetric block cipher called AES is used in CTR mode. --[[User:Neimod|Neimod]] 23:32, 20 June 2011 (CEST)<br /> <br /> <br /> How did you get this data? Did you find some way to dump 3DS cartridges? --[[User:Popoffka|Popoffka]] 09:15, 1 June 2011 (CEST)<br /> :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. --[[User:Neimod|Neimod]] 10:03, 1 June 2011 (CEST)<br /> <br /> Do you have any method to run a Dump? and did you find the key for the ctrtool? --[[User:Stevechou|Stevechou]]<br /> :Nope on both questions. --[[User:Neimod|Neimod]] 17:33, 25 June 2011 (CEST)<br /> <br /> There's code in ctrtool that takes the AES counter value from some partition ID and type. I can't help but wonder, how do you know that the counter value is generated this way? And if we know that, isn't it a start to finding out the key? --[[User:Luigi2us|Luigi2us]] 20:17, 25 June 2011 (CEST)<br /> :Sorry this information cannot be disclosed. --[[User:Neimod|Neimod]] 05:17, 27 June 2011 (CEST)<br /> <br /> Anyway, can you read the encrypt datas?</div>
