The FinderOuter, a bitcoin recovery tool (v0.19.1 2024-01-24)

[Viko19]

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.

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

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.

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.

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.

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.
