# RN-BitcoinJS (rn-bitcoinjs-lib)

#### Note: Great news! This library is no longer required for bitcoinjs-lib versions 5.1 and up. [Please use this Gist instead to get your RN project up and running.](https://gist.github.com/coreyphillips/4d45160fed016417a5f583f179c2cbdb)

This is a React Native compatible version of [bitcoinjs-lib](https://github.com/bitcoinjs/bitcoinjs-lib), a javascript Bitcoin library for node.js and browsers.  Written in TypeScript, but committing the JS files to verify.

Released under the terms of the [MIT LICENSE](LICENSE).

## Should I use this in production?
If you are thinking of using the *master* branch of this library in production, **stop**.
Master is not stable; it is our development branch, and [only tagged releases may be classified as stable](https://github.com/coreyphillips/rn-bitcoinjs-lib/tags).

## Can I trust this code?
> Don't trust. Verify.

You shouldn't trust or rely on this repo for anything other than testing. To setup bitcoinjs-lib (5.0.5) in your RN project, please follow the how-to below:
[RN BitcoinJS-Lib (5.0.5) Setup](https://gist.github.com/coreyphillips/9719d7e4b1f6042b993f548d2083cee8)

If you have any difficulty with the setup instructions below and need a repo for reference, feel free to clone, review and experiment with the pre-built RN repo here: [RNBitcoinJS](https://github.com/coreyphillips/RNBitcoinJS)

We recommend every user of this library and the [bitcoinjs](https://github.com/bitcoinjs) ecosystem audit and verify any underlying code for its validity and suitability.

Mistakes and bugs happen, but with your help in resolving and reporting [issues](https://github.com/bitcoinjs/bitcoinjs-lib/issues), together we can produce open source software that is:

- Easy to audit and verify,
- Tested, with test coverage >95%,
- Advanced and feature rich,
- Standardized, using [prettier](https://github.com/prettier/prettier) and Node `Buffer`'s throughout, and
- Friendly, with a strong and helpful community, ready to answer questions.

## Documentation
Presently,  we do not have any formal documentation other than our [examples](https://github.com/bitcoinjs/bitcoinjs-lib#examples), please [ask for help](https://github.com/bitcoinjs/bitcoinjs-lib/issues/new) if our examples aren't enough to guide you.

## Installation
``` bash
yarn add rn-bitcoinjs-lib
```

Typically we support the [Node Maintenance LTS version](https://github.com/nodejs/Release).
If in doubt, see the [.travis.yml](.travis.yml) for what versions are used by our continuous integration tests.

**WARNING**: We presently don't provide any tooling to verify that the release on `npm` matches GitHub.  As such, you should verify anything downloaded by `npm` against your own verified copy.

## Setup

### React Native
Install the following dependencies:
``` bash
yarn add buffer-reverse react-native-randombytes crypto buffer@5
yarn add --dev rn-nodeify
react-native link react-native-randombytes
```
Add the following to your script in package.json:

``` javascript
"postinstall": "rn-nodeify --install buffer,stream,assert,events,crypto,vm --hack && cd node_modules/bs58 && yarn add base-x@3.0.4 && cd ../../"
```

Install any remaining dependencies and run postinstall.
 NOTE: (If you receive an error about "shim.js" not existing just run `yarn install` again):

``` bash
yarn install
```

Add the following to shim.js:
``` javascript
if (typeof Buffer.prototype.reverse === 'undefined') {
  var bufferReverse = require('buffer-reverse');

Buffer.prototype.reverse = function () {
    return bufferReverse(this);
  };
}
```

Add/Uncomment "require('crypto')" at the bottom of shim.js:

``` javascript
require('crypto')
```

Finally:

``` bash
yarn install
```

**Usage**
``` javascript
import "./shim";
const bitcoin = require("rn-bitcoinjs-lib");
const keyPair = bitcoin.ECPair.makeRandom();
const { address } = bitcoin.payments.p2pkh({ pubkey: keyPair.publicKey });
console.log(address);
```

Crypto is hard.

When working with private keys, the random number generator is fundamentally one of the most important parts of any software you write.
For random number generation, we *default* to the [`randombytes`](https://github.com/crypto-browserify/randombytes) module, which uses [`window.crypto.getRandomValues`](https://developer.mozilla.org/en-US/docs/Web/API/window.crypto.getRandomValues) in the browser, or Node js' [`crypto.randomBytes`](https://nodejs.org/api/crypto.html#crypto_crypto_randombytes_size_callback), depending on your build system.
Although this default is ~OK, there is no simple way to detect if the underlying RNG provided is good enough, or if it is **catastrophically bad**.
You should always verify this yourself to your own standards.

This library uses [tiny-secp256k1](https://github.com/bitcoinjs/tiny-secp256k1), which uses [RFC6979](https://tools.ietf.org/html/rfc6979) to help prevent `k` re-use and exploitation.
Unfortunately, this isn't a silver bullet.
Often, Javascript itself is working against us by bypassing these counter-measures.

Problems in [`Buffer (UInt8Array)`](https://github.com/feross/buffer), for example, can trivially result in **catastrophic fund loss** without any warning.
It can do this through undermining your random number generation, accidentally producing a [duplicate `k` value](https://www.nilsschneider.net/2013/01/28/recovering-bitcoin-private-keys.html), sending Bitcoin to a malformed output script, or any of a million different ways.
Running tests in your target environment is important and a recommended step to verify continuously.

Finally, **adhere to best practice**.
We are not an authorative source of best practice, but, at the very least:

* [Don't re-use addresses](https://en.bitcoin.it/wiki/Address_reuse).
* Don't share BIP32 extended public keys ('xpubs'). [They are a liability](https://bitcoin.stackexchange.com/questions/56916/derivation-of-parent-private-key-from-non-hardened-child), and it only takes 1 misplaced private key (or a buggy implementation!) and you are vulnerable to **catastrophic fund loss**.
* [Don't use `Math.random`](https://security.stackexchange.com/questions/181580/why-is-math-random-not-designed-to-be-cryptographically-secure) - in any way - don't.
* Enforce that users always verify (manually) a freshly-decoded human-readable version of their intended transaction before broadcast.
* Don't *ask* users to generate mnemonics, or 'brain wallets',  humans are terrible random number generators.
* Lastly, if you can, use [Typescript](https://www.typescriptlang.org/) or similar.

### Node.js
Use [bitcoinjs-lib](https://github.com/bitcoinjs/bitcoinjs-lib)

### Browser
Use [bitcoinjs-lib](https://github.com/bitcoinjs/bitcoinjs-lib)

### Typescript or VSCode users
Type declarations for Typescript are included in this library. Normal installation should include all the needed type information.
