I tried FinderOuter but it’s taking more than a month and gives more than 100 private keys.

This is weird. With 11 missing characters, I'd expect millions of valid private keys. If you know the address, you should know which one you need. But if you don't know the address, you should have many more private keys.

Anyway, with just 100 private keys, you could even import them into a new Electrum wallet to see if any of them have transactions. See this post to restore Segwit addresses.

I have a private key with 11 character’s missing from 3 to 6, 25 to 27 and 48 to 51. I understand that last four characters are the checksum. I tried FinderOuter but it’s taking more than a month and gives more than 100 private keys. I do not which software I can use to locate the correct private key. Any advice, please let me know.

Version 0.19.1 (2024-01-24)
https://github.com/Coding-Enthusiast/FinderOuter/releases/tag/v0.19.1.0

Fix a bug in VMs where FinderOuter crashed if user entered an invalid input
Move to .net 8 and compile binding (UI)
Some cleanup and UI fixes

This minor release is fixing a critical bug but also moves to the new .net 8 which required changing UI bindings to compiled binding to prevent UI code from being trimmed. This also further decreases the binary sizes (~8%).
The backend (Bitcoin.Net) is also updated to 0.26.0 with improvements and bug fixes in ECC implementation which should also bring some small optimization.

Version 0.19.0 (2023-11-15)
https://github.com/Coding-Enthusiast/FinderOuter/releases/tag/v0.19.0.0

Add settings to define the number of threads used in parallelism + KB entry
Old Electrum mnemonics are still not supported but they will be rejected with a clear message
Various bug fixes, code improvements, additional tests and some UI fixes

Two major changes in this release are migration to the new Avalonia UI version 11.0 and .Net 6 with trimming option that reduces the binary size by roughly 40%. Even though most UI bugs were fixed before releasing v0.19 there may still be some uncaught ones, please report them on GitHub (or here) if you encounter any.

Hi dev, a suggestion : could you make it so the user could select how many threads to be used? Since it uses everything a CPU can offer, usually it just hangs if the load is too much, unless you go to task manager on windows and limit CPU usage, but having an option to set one time and the ability to save the user settings would be great.

https://github.com/Coding-Enthusiast/FinderOuter/commit/09466f3e9fe2b57fa158c1f61add98e15cb6973d
This was added under an expander on the side with the name "Settings" that will allow you to set the number of threads the parallel loops use based on the number of cores .net can detect.
The max value here may not be accurate in case the system has more than one processor group or has CPU utilization limit. I'll probably add an override option to go beyond that limit as a more advanced feature since going beyond the thread limit could potentially slow down the process.
This also needs some guides on how it should be used etc. in our KnowledgeBase page which I'll add before v0.19.0 is released.

PS. If you build at the given commit above, know that there is currently a bug in our UI where the slider appears to be at the minimum value (1) when the application starts but the actual value is set correctly to the maximum number of threads. This is fixed in the new AvaloniaUI 11.0 which we need to upgrade to but it takes time due to the breaking changes in the UI framework.

Hi, need to find private key for bitcoin wallet. Part of this key is 35 characters, I know how to find other characters, is there a program for sorting characters with an indication of mandatory ones.
I would appreciate a tip on the bitcoin part

It becomes a really huge machine! Do you have any plans for the next release(s)?

Saving progress and restoring partial search?
Using a range in derivation path?

I was briefly comparing what you have with features of 'lostword' and looks like you have (almost) all

For now until version 1.0 I'm focusing on increasing my test coverage and finding bugs while improving the printed reports and messages.
After that I'll start investigating how to add GPU support.
Anything else I'll try to squeeze in if I have any idea of how to implement them efficiently without needing any significant code change.

Version 0.18.0 (2023-06-23)
https://github.com/Coding-Enthusiast/FinderOuter/releases/tag/v0.18.0.0

Improve the returned message (errors and reports)
New feature: time estimation. Addresses #30 [1]
New feature: Add an AutoCompleteBox to mnemonic recovery option to suggest words based on letters the user entered [2]
Various bug fixes, code improvements and some additional tests

[1] This will show the number of keys that were checked so far and an estimated speed in number of keys(permutations) per second and the estimated time remaining until the entire search space is checked. Note that in most cases the actual key could be found before the entire space is searched.
See issue #30 for information on its limits.

[2] When modifying the mnemonic search-space by entering possible words, user can switch to the Auto Complete mode so that a suggestion list opens up based on the letters that were entered so far. This should also make it easier to see all words that contain certain letters (like the image below with words containing "xi").
Mode can change any time using the switch button.

What's the maximum number of allowed characters in the passphrase? It says 100 is too much. I don't think my passphrase is 100 but I put that since it's the maximum a Ledger will allow, which is what I used.

Brute-forcing 100 characters will never ever succeed. You'll probably have a very hard time with 10 characters already, if your password is that long your only chance is to remember (most of) it.

If I do remember most of it, where do I enter that data in FinderOuter?

Hello.

I'm trying to find my passphrase. I have the 24 word seed phrase.
Where can I enter the (presumed) words known for the passphrase? If I try in Customchars, it says to remove duplicate letters.

Also having a windows compiled version would be greatly appreciated.

Under releases on GitHub there is always a zip file containing the binaries for Windows.
https://github.com/Coding-Enthusiast/FinderOuter/releases/download/v0.17.0.0/FinderOuter-0.17.0.0-Win64SCD.zip

As for your other suggestions, manual key generation doesn't really fit into a "recovery tool" so it can't be added to FinderOuter.

Some suggestions, it would be nice to have the ability to do SHA256 RIPEMD160, HASH-160, convert private key to u/compressed public keys, convert WIF to private key and vice versa, base58 checksum decode/ encode. Converting public keys to addresses, converting address to RIPEMD160, vice versa.

Basically manual key generator etc, It's hard to use several online tools for just computing a bitcoin address.
Also having a windows compiled version would be greatly appreciated.
I know that I might sound too demanding, but these are just suggestions.

Could you give me a price and time estimate please?

I'd say roughly 1-2 hundred millions of addresses can be encoded sequentially this way per second per core. Although since we are talking about 10¹⁶⁰ addresses, the size is going to be massive and won't fit in any memory or storage space.

Oh hello dear dev, it seems GPU support is at the end of your roadmap. Anyway, since you know some expert stuff about coding, I was wondering how much could it cost if we were trying to create a database of addresses like this for example:

Starting from 1 and going to the end of base 58 characters, even we could search for our addresses to see all the similar ones on a page, maybe 200 addresses shown per page.

Could you give me a price and time estimate please?

We are heading for the first stable version (v 1.0) by fixing as many little bugs as possible and improving the code in general. Since that may take a while I'll try to publish more beta versions that act as pre-releases to 1.0 from now on. As always follow the roadmap to see updates on when new features like GPU support could be added.
Here is version 0.17.0 with lots of little improvements:

Version 0.17.0 (2023-02-27)
https://github.com/Coding-Enthusiast/FinderOuter/releases/tag/v0.17.0.0

Removed message signature verification
Solve issue #4 (not being able to enter words in CJK languages)
Completely rely on new Bitcoin.Net release for ECC (has some bug fixes and slight optimization)
Improve printed messages (errors and reports)
Improved how Base16, Base58 and MiniKey options handle configuring search-space which solves some bugs and returns better messages
Return a comprehensive message when an input contains invalid characters (the invalid char and index)
Small UI improvements
Various small bug fixes, code improvements, code cleanup and lots of new tests

PS. FinderOuter is 3 years old

Hi there, please let me know the commands required to install on Ubuntu/Debian OS after unzip, from Finderouter-master folder. Thanks

Everything is already explained in ReadMe file. If you have the source code and want to compile Step 2 or Step 3 if you have the complied binaries and want to run.
