# MnemonicSwift

[![Build Status](https://travis-ci.org/zcash-hackworks/MnemonicSwift.svg?branch=master)](https://travis-ci.org/zcash-hackworks/MnemonicSwift)

An implementation of BIP39 in Swift. MnemonicSwift supports both English and Chinese mnemonics.

This library is a fork of [MnemonicKit](https://github.com/keefertaylor/MnemonicKit). This fork provides provides support for BIP39 using CryptoKit.

## Installation

### CocoaPods
MnemonicSwift supports installation via CocoaPods. You can depened on MnemonicKit by adding the following to your Podfile:

```
pod "MnemonicSwift"
```

#### Carthage

If you use [Carthage](https://github.com/Carthage/Carthage) to manage your dependencies, simply add
MnemonicKit to your `Cartfile`:

```
github "zcash-hackworks/MnemonicSwift"
```

## Usage

### Generate a Mnemonic

```swift
  let englishMnemonic = Mnemonic.generateMnemonic(strength: 64, language: .english)
  let chineseMnemonic = Mnemonic.generateMnemonic(strength: 128, language: .chinese)
```


### Generate a Mnemonic from a Hex Representation

```swift
  let hexRepresentation: String = ...
  let mnemonic = Mnemonic.mnemonicString(from: hexRepresentation)
  print("Mnemonic: \(mnemonic)\nFrom hex string: \(hexRepresentation)")
```

### Generate a Seed String

```swift
  let englishMnemonic = Mnemonic.generateMnemonic(strength: 64, language: .english)
  let passphrase: String = ...
  let deterministicSeedString = Mnemonic.deterministicSeedString(from: mnemonicString,
                                                                 passphrase: passphrase,
                                                                 language: .english)
  print("Deterministic Seed String: \(deterministicSeedString)")
```
