3DS:Seedminer: Difference between revisions

{{hatnote|This article is only for information and non-standard usage of Seedminer. For information on how to use Seedminer if your system can add friends, see the main guide's [[3dsguide:seedminer|Seedminer page.]]}}

'''Seedminer''' is a process used to find a 3DS family system's <code>movable.sed</code> (the system-unique encryption key) and is used in the majority of CFW installation methods on the latest firmware. At present, there are three main ways to derive <code>movable.sed</code>: the automated '''BFM (Bruteforce Movable)''' service, '''manual mining''', and '''Mii mining'''.

 

If you're interested, a presentation on Seedminer's technical aspects can be found [https://zoogie.github.io/web/34%E2%85%95c3 here].

If you can add friends, you should follow [[3dsguide:seedminer|the Seedminer page]] to use Bruteforce Movable to automatically mine your movable.sed.

 

* If BFM is '''inaccessible''' (the website is down), check [[#Bruteforce_movable_connectivity_and_uptime|this section.]] for more information.

* If BFM says that you are '''locked out''', [[Get_support|join our Discord server]] for assistance.

* If BFM says that it '''could not process your request''', read [[#Consoles made in 2011|this section]] for more information.

* If BFM is up and you wish to try manual mining anyway, see [[/Manual_Mining|here]].

 

 

 

 

If you have an already-hacked 3DS physically on hand, see [[/Manual_Mining|here]] to dump your LFCS and mine it yourself. If not, you will need to follow [[/Mii_Mining|Mii Mining]] instead.

The <code>movable.sed</code> file is a system-unique encryption key for the 3DS. It is supposed to have 128 bits of random encryption, which would be impossible to bruteforce with modern hardware. However, due to various flaws with Nintendo reusing code, the number of possible values is ~2^40 instead of 2^128, a decrease of 2^22 (''1 trillion trillion'', or 70%) from the expected value.

 

This is due to half of <code>movable.sed</code> being created from the LFCS (Local Friend Code Seed), a file which any hacked system that has the target 3DS as a friend can dump, and another quarter being mathematically related to the LFCS. These factors make it possible to derive the encryption key with modern consumer-level hardware.<br>

 

If the system cannot add friends, a Mii QR code can be bruteforced to derive the same information that would be exchanged in a friend exchange. However, the smaller amount of data available for this method means that this takes a significant amount of extra time.

If you can obtain the LFCS, needing to mine only ~30% of the potential 2^128 values makes it easy to bruteforce with almost any dedicated GPU - even older models such as an Nvidia GTX 760. Integrated graphics are not powerful enough and may take multiple hours.

 

If you cannot obtain the LFCS, Mii mining takes significantly longer (up to 2 hours, depending on GPU strength) since it must also bruteforce the full LFCS before it can bruteforce the random values. Attempting to use integrated graphics for this method may result in it taking upwards of a day.

 

Once created, the <code>movable.sed</code> created can be used to decrypt any system data on your SD card (such as digital game save data). Because a bruteforced <code>movable.sed</code> only contains the data necessary to decrypt system data (and not other data that is used to verify that it is valid), it is '''not recommended''' to inject a bruteforced movable into your NAND (though, it won't [[brick]] your system).

<code>movable.sed</code> is within bruteforcing territory with modern dedicated graphics cards; with optimizations and volunteers, the process can be entirely automated with mining times of 5 minutes or less. [[https://seedminer.hacks.guide Bruteforce Movable]] is a working implementation of this, and is the method used for Seedminer in our guide.

If you want to volunteer some of your GPU power for mining others' movables, go to the Seedminer website and read the "Mine for BruteforceMovable" header for isntructions.

 

If your system is altered in certain ways, you will be unable to follow one or more of the Seedminer methods. Some examples:

If your console is a launch model Old 3DS (made in 2011), its <code>movable.sed</code> cannot be derived through Seedminer. Therefore, these consoles '''cannot use any Seedminer method'''.

 

Any system that has received a system transfer from a launch model will also be unminable, but will become minable again after a system format. If your console appears to be impossible to mine, either do a system format first or look into an alternate exploit path.

 

For alternate paths, [[3dsguide:installing-boot9strap-(kartdlphax)|kartdlphax]] and [[3dsguide:ntrboot|ntrboot]] are both viable options, but if you cannot do either of these without significant extra effort, you should see if you have the resources needed for [[3DS:Alternate_Exploits|one of these paths.]]
