Topic: The FinderOuter, a bitcoin recovery tool (v0.16.0 2022-09-19) - page 5. (Read 3882 times)

No. UI isn't consuming that much CPU power, it is just a thread that will be updated every now and then.

Not yet.

10 words out of how many? 2 missing out of 12 takes only an hour on my old PC, having 10 out of more like 24 is impossible to brute force.

It will stop as soon as it finds the correct combination of words and prints the result.

Is FinderOuter available for console only? I believe that it would go faster. Also question, can I run it with my gpu? I'm brute forcing an mnemonic with 10 words and it has to search among 4.1 million mnemonics. I left it all night, it seems to be in the middle.

Edit: Another question, does it searches until it finds the correct mnemonic or does it try all the possible combinations first? As I said I've reached the middle and I want to know if my chances are getting smaller.

Hi there Coding Enthusiast,
got it working now, thanks again for this great piece, merry christmas,

Version 0.6.0 is released.
https://github.com/Coding-Enthusiast/FinderOuter/releases/tag/v0.6.0.0
See changelog for details.

• Move to .net 5.0
• Added small icons at the bottom showing the current state of the program
• New recovery option: ELectrum mnemonics
• Base16 recovery now has more options for secondary input (to check against)
• Add a new word list to mnemonic recovery: Portuguese

As you may already know FinderOuter has always been a bitcoin recovery tool but we may add altcoin recovery options some day.
By request I created a new branch for recovering Tron private keys, it can recover a hexadecimal Tron private key if you have the damaged hex and your public key or address. https://github.com/Coding-Enthusiast/FinderOuter/tree/Tron

Glad it worked out for you but you should know that it is not safe to handle your private keys and other secrets on Windows specifically if the system is what you regularly use for everything else too. This is why I have only released compiled version for Linux.

Hi Coding Enthusiast, i cant compile it   broken os.
could you get a compiled one up and ready to use, for windows 10 probably,
thanks a lot, just did fix the not compiling issue, used ps net .

Version 0.5.0 released (The Parallelization Update)

This is the parallelism update with tons of optimization from a small 10% speed gain to more than 1800% in some cases.  
- Most of these optimizations are in Base58 recovery option.  
  - Compressed and uncompressed private key recovery uses all available CPU cores for maximum speed and at 100% capacity.
  - Two special cases were added to recover private keys that are missing characters from their end (up to 9 missing for uncompressed and 11 for compressed is the default for now and can be recovered in less than a minute).  
  - Recovery of Base58 addresses and BIP-38 encrypted keys are also optimized the same way.
- Mini private key recovery
  - It uses all available CPU cores
  - It suffers from the known issue #9
  - The extra input has more options like other recovery options to enter different types of addresses or a public key.
- Mnemonic recovery
  - New wordlist added (Czech)
  - There is a simple checkbox now to set the key index itself to be hardened
  - It suffers from the known issue #9 whenever there is EC multiplication involved (private key to public key), otherwise if there weren't any the code will run at maximum efficiency using all cores at 100% (see 5th example in mnemonic recovery)

Other most notable changes:
- Now there is a progress bar at the bottom that will be used when recovering in parallel to show the progress so far. Other times when using single core the recovery process never takes up longer than a minute (usually less than 10 seconds) so progress bar is disabled.  
- Addition of more examples for each recovery option.  
- Various code improvements and bug fixes.

Version 0.4.1 is released.
https://github.com/Coding-Enthusiast/FinderOuter/releases/tag/v0.4.1.0
See changelog for details.
This is a minor version released with a little bit of delay that introduces the Example button. It is an easy and quick way of seeing how to fill different text boxes. Hopefully it can clear some confusions that some beginners may have with things such as BIP-32 paths.

Short answer is it's impossible to recover this private key since the number of possible keys to check is enormous.

You'll need to construct and compute 1,449*10¹⁸ hashes, in comparison current total bitcoin hashrate (the entire bitcoin mining power) is about 100*10¹⁸ and that is hash of a rather fixed input that doesn't have the same additional computation step on each round. That means even if you had all the ASICs operating today and had a way of modifying them to compute the hash you want, you still wouldn't even be able to go through 5% of the cases.

On top of that since the number of missing characters is huge, the number of correct results is going to be large and in order to go through all of them there is another bottleneck which is computation of public key and if needed the address to compare with an input (FinderOuter doesn't do that in current version).

---

PS. I don't want to get your hopes up but there may be a small chance if you have your public key. I still haven't looked into the algorithm (Pollard's kangaroo) but it may be possible if we could get a manageable range of keys from what you already have.

It is a privatekey with 51 characters, I lost 12 characters. I lost everything?

Do you mean a private key with 12 characters left? Forget it!
If it's an address, 12 characters is enough to check if it holds funds.

Hello!

I have an address with 12 characters left. Is it feasible to try to recover?

"Total number of keys to test: 1.449.225.352.009.601.191.936"

Could this take years?

Version 0.2.0 is released.
https://github.com/Coding-Enthusiast/FinderOuter/releases/tag/v0.2.0.0
See changelog for more details.
Most notable changes are:
- Replacing backend with the well tested Bitcoin.Net library which improves performance and fixes some bugs
- Added 2 new features: recovering Base-58 addresses and BIP-38 encrypted keys
- Fix some bugs including a bug that prevented the FinderOuter from running on Ubuntu 20

Did you try to build the project from source code and faced difficulties or did you try to run the compiled version (the 27 MB file called v0.1.2.0.zip) and had problems?
And please mention the difficulties you encountered explicitly so that I could improve the project and make things easier.

Thank you for all Coding Enthusiast. But that's very difficult to follow for people who are not involved in IT, I tried all night long to launch FinderOuter but that doesn't work... maybe I am too idiot.

Sorry, The FinderOuter doesn't support wallet files (bitcoin core backups) yet.
And please ask your questions in English so that I don't have to use Google Translate.

Bonjour l'équipe,
Je voudrais savoir ?
Les sauvegarde bit coin core :
Peuvent elles être récupérer avec le logiciel? (FinderOuter)
Je n'arrive pas à le télécharger.
De plus j'ai pas ubuntu . Juste Windows 8.
Merci pour votre réponse
(Sauvegarde  bitcoin core dans un fichier)
( je n'ai pas réussis avec btcrecover ou pywallet)

I'd recommend doing the following (more info here: https://github.com/Coding-Enthusiast/FinderOuter#running-the-finderouter):
1. Download FinderOuter release or source and build it yourself (deterministic builds and PGP signature will be added in near future)
2. Download Ubuntu
3. Verify Ubuntu's iso
4. Disconnect network cable (to remain offline)
5. Boot from a DVD or USB
6. Run FinderOuter

You may find it easier if you used Visual Studio (https://visualstudio.microsoft.com/vs/mac/), if you install that then all you have to do is to open the solution file (FinderOuter.sln) and change solution configuration to "Release" and build using Build > Build solution from menu or press Ctrl+Shift+B and you'll find the binary at

If you didn't want to download VS. then MSDN has some good posts to get you started on how to use dotnet commands.
https://docs.microsoft.com/en-us/dotnet/core/get-started
An example: https://docs.microsoft.com/en-us/dotnet/core/tutorials/cli-create-console-app
the dotnet build command: https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-build
Basically you'll have to run:

To have a comparison the Base-58 part searches for 1.4 million keys per second but the Base-16 part is searching for 1200 keys/sec on my PC.
I am trying to optimize ECC (which is what slows things down here) but unfortunately that will take a very long time to be ready.

hey Coding Enthuziast thank you for the update , i was not expected to be done that soon . 

i've downloaded your software aaand  ...now it seem i have another obstacle (( oooh man , it never eeeends (( 

the software you made is for Ubuntu Linux , well i have a macbook ,anyway i also have  a virtual machine windows 10 app installed ( the name of application is Parallels Desktop-it is a virtual Windows 10 with full licence wich is running inside my IOS ) 

 I opened the virtual windows 10 and tryed to install inside , a virtualbox with ubuntu !   something like : Ubuntu running inside Windows 10 , running inside an IOS , a mess, i know )))))     but they don't let do do that (((    i think i can not run a virtual machine inside another virtual machine

I've seen on github on your page some instructions for converting the software and make it run in windows but i can not handlle them   how can i make it run on Windows 10 or IOS??? with instructions step by step for noobs ....  :/ 

Hey , and by the way , you said the soft will run verry slow for base16 privatekeys, well , just curios.... how slow ?    like 1/2 private keys per seconds ??

with all of that beeing said , i want to thank you again for your efort      

Version 0.1.2 is released.
https://github.com/Coding-Enthusiast/FinderOuter/releases/tag/v0.1.2.0
See changelog for more details.
Most notable changes are:
- New feature: missing chars in base-16 encoded keys (unfortunately unlike other options this is very slow for now)
- Simplified Base-58 option to no longer need a checkbox for special case.
- Base-58 will return a friendly error message if a full private key was entered and was invalid.
- Some optimization and code cleanup.
