Version 0.12.0

This version introduces a new feature: recovering mnemonic (BIP39, Electrum) passphrase recovery.
See Changelog for details.

Binaries for 3 different operating systems are available as zip files below. All 3 are self-contained releases that are ready to run since they contain the required .Net assemblies (there is no need to download and install .Net).

• Win64SCD is for 64-bit Windows OS
• Linux64SCD is for 64-bit Linux OS
• Osx64SCD is for 64-bit macOS

For any other operating systems or architectures (eg. Win32, LinuxARM,...) you have to compile FinderOuter yourself.

Version 0.11.0

This release focuses on optimizing SHA and changing Base58 algorithm which improve recovery speed.
See Changelog for details.

Version 0.10.0

This release focuses on optimizing ECC and solving issue #9 which greatly improves recovery speed.

Version 0.9.0

This version introduced a Help window at startup and started a Knowledge Base to help explain different parts and concepts in Bitcoin.
There is also a new option: Missing encoding which helps detect encoding of an input string.
See Changelog for details.

The binary is tested on Ubuntu 20.04 x64.

Version 0.8.0

This version introduces 2 new recovery options: BIP-32 derivation path and Armory paper backup. UI is also slightly improved.
See Changelog for details.

The binary is tested on Ubuntu 20.04 x64.

Version 0.7.0

This versions moves to AvalonieUI v0.10 and improves the looks of FinderOuter.
See Changelog for details.

Like previous releases the binaries are tested on Ubuntu 20.04 x64.

Version 0.6.0

This version introduces new mnemonic recovery option for Electrum mnemonics and adds more improvement to Base16 recovery option.
See Changelog for details.

From this version FinderOuter migrates to the new .net 5. Like previous versions this release is self-contained (doesn't need downloading anything like .net) and is tested on Ubuntu 20.04 x64. The release is using the new app trimming introduced in .net 5 to reduce the size, if you face any issues please report them.

Version 0.5.0

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

A minor release introducing the Example button.
See Changelog for more details.

Version 0.4.0

This version introduces a new feature: recovering missing mnemonic words for BIP-39.
Please note that FinderOuter is still a single-thread application utilizing CPU only, which means it is not taking advantage of the full potential of your hardware and can become a lot faster when the multi-thread update comes.
See Changelog for more details.
