<p>Stevechou: /* Do you have any method to run a Dump? and did you find the key for the ctrtool? */ new section</p> <hr /> <div>How 3DS system judge encryption type? [[User_talk:Matyapiro|Matyapiro]]<br /> <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 /> <br /> - moved this comment to the filetypes page where it's more appropriate<br /> <br /> == Do you have any method to run a Dump? and did you find the key for the ctrtool? ==<br /> <br /> Do you have any method to run a Dump? and did you find the key for the ctrtool?</div>
