MnemonicKit        

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

This library is originally forked from CKMnemonic: https://github.com/CikeQiu/CKMnemonic. Modifications are made for non-throwing APIs and support on OSX as well as iOS. Credit for most of this work is given to work_cocody@hotmail.com, qiuhongyang@askcoin.org.

Installation

CocoaPods

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

pod "MnemonicKit", :git => 'https://github.com/keefertaylor/MnemonicKit.git'

Usage

Generate a Mnemonic

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

Generate a Mnemonic from a Hex Represetation

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

Generate a Seed String

  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)")
