3DS:Seedminer: Difference between revisions

Revision as of 02:32, 1 November 2022

Seedminer, with three implementations known as BFM (Bruteforce Movable), Manual Mining, and Mii Mining, is a process used to find a 3DS family system's movable.sed, (the system-unique encryption key) and is used in the majority of CFW installation methods. If interested, a presentation on Seedminer's technical aspects [can be found here.]

Requirements

If BFM is inaccessible or you encounter issues using the site, join our Discord server and ask for help.

All systems that can access the HOME Menu and either add a friend or create Miis can use Seedminer, but which methods are available will depend on your system's ability to add friends and whether you can access BFM.
The potential outcomes are as follows:

See the seedminer page to use BFM and automatically mine your movable.sed.

If BFM is down, check this section.
If BFM says it could not process your request, read this section for more information.

If BFM is up but you wish to try manual mining anyway, see here.

Try another wireless connection or get closer to your router. If you can use it, BFM is significantly easier.

If you have an already-hacked 3DS on hand, see here to dump your LFCS and mine it yourself.
If you do not have this, you will need to do Mii Mining instead.

See here to do an altered version of the manual process.

How it works

Movable security characteristics

The movable.sed 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 - but 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 expected.
This is due to half of movable.sed 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, which makes it very easy to bruteforce quickly.
If the system cannot add friends, a Mii QR code also has some of this information. However, the smaller amount of info means the LFCS must also be bruteforced, which takes a significant amount of extra time.

Mining the movable

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 extremely old models such as an Nvidia GTX 760. Integrated graphics are not powerful enough, however, 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 movable.sed created can be used for nearly all purposes, but some of the data is ignored for bruteforcing - as such, it is not recommended to inject a bruteforced movable into your NAND, though it will not brick your system.

Automation and optimization

it is within bruteforcing territory - with optimizations and volunteers, the process can be entirely automated with mining times of 5 minutes or less. [Bruteforce Movable] is a working implementation of this, and is the method used for Seedminer in our guide.

How to mine for others on BFM

Go to the seedminer website and read the "Mine for BruteforceMovable" header if you want to volunteer some of your GPU power for mining others' movables.

Limitations

System issues

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

If your console has no Friend Code or is banned, you will need to do Mii Mining.
If your system is unable to use Wi-Fi, you will need a second, already-hacked 3DS to follow Manual Mining. If you do not have this, you will need to do Mii Mining.

Consoles made in 2011

If your console is a launch model o3DS (made in 2011), its movable.sed will be made 'correctly' and cannot be mined. These consoles cannot use any Seedminer method.
Any system that has received a system transfer from a launch model will also be unmineable, but will become mineable 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, kartdlphax and ntrboot are both viable options, but if you cannot do either of these without significant extra effort, also check if you have the resources for one of these paths.

BFM connectivity and uptime

Although BFM is generally very stable, it requires your computer to be able to connect to either https://seedminer.hacks.guide or https://bfm.nintendohomebrew.com. If BFM is down, your connection is too unstable/slow, or an internet block is disabling access to both of these websites, then join our Discord server for help.

-=== Movable security characteristics ===
-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 values that have to be decrypted is ~2^40 instead of 2^128 (a decrease by a factor of roughly ''100 septillion'' 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.
-=== Mining the movable ===
-If you can obtain the LFCS, the enormous reduction in difficulty makes it easy to bruteforce the full <code>movable.sed</code> with almost any dedicated GPU - even older models such as an Nvidia GTX 760. Integrated graphics are still weak by these standards, however, and will likely take a few hours.
-If you cannot obtain the full LFCS but can obtain a Mii QR code, it will take 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 take 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).

-=== Consoles with mismatched movables ===
+==Limitations==
-There is a known issue, disproportinately affecting older consoles more than new ones, that makes the affected consoles' true <code>movable.sed</code> unable to be mined. Therefore, these consoles '''cannot use any Seedminer method'''.
-The only confirmed source of this issue is in consoles that have been shipped to Nintendo for repairs previously. Consoles that were manufactured before February 2012 experience this at a far higher rate than other consoles, but the cause in those cases is unknown.

-Any console that has received a system transfer from a console affected by this will also be temporarily made 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.
-[[3DS:Alternate Exploits/Preparing menuhax67 (kartdlphax)|kartdlphax]] and [[3dsguide:ntrboot|ntrboot]] are the preferred alternate 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.]]
