Build Status

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

This library is a fork of MnemonicKit. This fork provides provides support for BIP39 using Crypto.

NOTE to 1.0.0 users: If you are using 1.0.0 in your project, we no longer maintain that version. Upgrade to 2.0.0 immediately.

pod "MnemonicSwift"

github "zcash-hackworks/MnemonicSwift"


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 Representation

  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,

  print("Deterministic Seed String: \(deterministicSeedString)")
