# Rudefox Burrow
|
||||
|
||||
Rudefox provides a pair of command line tools for the creation and management of Bitcoin wallets.
|
||||
*Offline Bitcoin Seed Generation and Wallet Tool*
|
||||
|
||||
+ Use `burrow` on an air-gapped single-board computer, like a Raspberry Pi, to generate new seed words, obtain addresses and extended public keys from existing seed words and sign PSBT transactions offline.
|
||||
+ Use `reynard` on a connected ("hot") device to view your balance and utxo's and to create new, unsigned transactions.
|
||||
Use Burrow on an air-gapped, single-board computer, like a Raspberry Pi, to generate new seed words, derive addresses and extended public keys from existing seed words or sign PSBT transactions offline. Check out the self-audited seed generation feature: [ShowMyWork](https://rudefox.io/blog/2020-07-16-show-my-work.html).
|
||||
|
||||
## Unique Feature: ShowMyWork
|
||||
[Rudefox Burrow](https://rudefox.io/burrow/) is released under the [MIT License](LICENSE.md) by B.J. Dweck
|
||||
|
||||
[**Rudefox ShowMyWork**](https://rudefox.io/blog/2020-07-16-show-my-work.html) is a feature of Burrow that enables non-technical end-users to audit the seed generation process in order to verify that the generated seed is derived directly from [8-sided dice](https://www.amazon.com/dp/B07XPMV4DQ/) rolls and a set of lookup-tables. Read more [here](https://rudefox.io/blog/2020-07-16-show-my-work.html).
|
||||
## Getting Started
|
||||
|
||||
If you simply want to dive in and try your hand at generating a self-audited seed, see the [Burrow Quick Start](https://www.rudefox.io/burrow/quick-start.html) guide.
|
||||
|
||||
## Build
|
||||
|
||||
### Linux
|
||||
|
||||
* Install the Java 8 SDK (Java 8+ is not already installed)
|
||||
|
||||
```bash
|
||||
alice@cold.machine:~$ burrow mnemonic -i8 --bits 128
|
||||
|
||||
Input 11 x 8-sided dice rolls [1-8]: 12345678123
|
||||
|
||||
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 1 | 2 | 3 |
|
||||

sudo apt-get install -y openjdk-8-jdk-headless
|
||||
```
|
||||
|
||||
## Menemonic Generation
|
||||
* Clone the repository and build
|
||||
|
||||
```bash
|
||||
alice@cold.machine:~$ burrow mnemonic --interactive --dice-entropy --bits 128
|
||||
Input 50 dice rolls [1-6]: 234322343242422344161254151
|
||||
Input 23 more dice rolls [1-6]: 33116265515343114314456
|
||||
Mnemonic Sentence: mountain tilt wing silk rude fox almost volume wine media verify card
|
||||
git clone https://git.rudefox.io/rudefox/burrow.git
|
||||
cd burrow
|
||||
./gradlew build distTar
|
||||
```
|
||||
|
||||
### Mnemonic Options
|
||||
|
||||
```bash
|
||||
usage: burrow mnemonic
|
||||
-b,--bits <128|160|192|224|256> bits of entropy (default: 256)
|
||||
-d,--dice-entropy use dice entropy source
|
||||
-e,--events <EVENT_STRING> string representing events from entropy source
|
||||
-h,--help display help message
|
||||
-i,--interactive use interactive command line mode
|
||||
```
|
||||
|
||||
## Xpub Export
|
||||
|
||||
```bash
|
||||
alice@cold.machine:~$ burrow wallet --sentence "stove prefer lunch collect small orphan wasp size beyond auction
|
||||
guilt great" --passphrase apple

|
||||
```
|
||||
### QR Code Generation
|
||||
|
||||
```bash-qrcode
|
||||
alice@cold.machine:~$ burrow wallet --sentence "stove prefer lunch collect small orphan wasp size beyond auction
|
||||
guilt great" --passphrase apple -q
