walletlib

Unified interface to programmatically open and extract data from cryptocurrency wallet backup files

Quick Start with Docker - Start here if you simply need to dump the contents of a wallet file

Make sure that the files you are trying to open are in one directory.

$ docker pull jimzhou/walletlib:latest
$ docker run -v /path/to/your/wallet/folder:/app jimzhou/walletlib:latest wallet.dat -o wallet_output.txt --keys -p password

Output file will be in the directory with the wallet. --keys and -p are optional

Quick Start with installation

This module requires Python 3.7+

Note: prior to installation, make sure that BerkeleyDB 4.8+ is installed.

With Homebrew:

$ brew install berkeley-db@4

On Ubuntu

$ sudo apt-get install libdb++-dev python3-bsddb3

$ pip install walletlib

A convenient cli script is available after installation.

$ python -m dumpwallet wallet.dat -o output.txt

or

$ dumpwallet wallet.dat -o output.txt
$ dumpwallet wallet-protobuf -o output.txt --keys

Features

• Automatic reading of version byte and WIF prefix from default keys
• Dumping just keys or all data
