goethrecover

What is goethrecover?

goethrecover is a very simple tool written in golang to recover lost passphrase of Ethereum Wallets using a list of passphrases (dictionary attack). You can also add some prefix and suffix strings to these passphrases.

How to install goethrecover?

To run goethrecover you need to install golang from Install Golang

Add some packages using 'go get'

go get "github.com/ethereum/go-ethereum/accounts/keystore"
go get "github.com/naoina/toml"

Then build goethrecover

go build goethrecover.go try_unlock.go config.go

How does it works?

It is simple...

./goethrecover -h

Usage of ./goethrecover:
  -conf string
    	TOML file with some configuration (default "conf.toml")
  -passList string
    	Text file with one passphrase per line (default "passList.txt")
  -wallet string
    	Wallet file (default "wallet.json")

In conf.toml there are some configurations option. Lines with # are comments
See conf.toml example below:

#---CONFIGURATION FILE---
#Modify values as you wish

#testVariants is boolean value
#true: Prefix and Suffix variations are tested
#false: Prefix and Suffix variations are not tested
testVariants = true

#preSeq is an array of prefix strings to test
preSeq = [ "123", "2008", "FOX" ]
#postSeq is an array of suffix strings to test
postSeq = [ "456", "1995", "512"]

#preBrute section
[preBrute]
active = true
lenght = 3
chars = ['a', 'b', 'c']

[postBrute]
active = true
lenght = 3
chars = ['1', '2', '3']

If you want to try prefix and suffix you need to set: testVariants = true
-Set prefix and suffix strings
Otherwise set: testVariants = false

If you want to try brute force of prefix (preBrute) and/or suffix (postBrute) set:
active = true
lenght = 3 lenght of string to bruteforce
chars = ['a', 'b', 'c'] set of custom character

Example

./goethrecover -wallet "myWallet.json" -passList "myFavoritesPasswords.txt" -conf "myOwnConf.toml"

Conclusion

This is a very simple tool. I hope it will help you to recover your ethereum wallet. Feel free to suggest new features or improvements.
