    Modifier and Type Method Description
    java.lang.String byteToHex​(byte[] key)  
    HdWallet generateHdWallet​(java.lang.String mnemonicSeedPassword)
    creates a keyPair as well as a list of mnemonic seed words wrapped into HdWallet object, which can be used to restore the key (derived from BIP32/39 HD-Wallet generation) the number of seed words depends on the parameter defined in KeyPairServiceConfiguration
    KeyPair generateKeyPair()  
    HdKeyPair getNextKeyPair​(HdWallet mnemonicKeyPair)
    derives the next hardened key.
    void printChildKeyPair​(byte[] il, byte[] ir)  
    HdWallet recoverHdWallet​(java.util.List<java.lang.String> mnemonicSeedWords, java.lang.String mnemonicSeedPassword)
    recover keypair from given mnemonic seed word list with given seed password
    KeyPair recoverKeyPair​(java.lang.String privateKey)

    • generateHdWallet

      public HdWallet generateHdWallet​(java.lang.String mnemonicSeedPassword) throws AException
      Description copied from interface: KeyPairService
      creates a keyPair as well as a list of mnemonic seed words wrapped into HdWallet object, which can be used to restore the key (derived from BIP32/39 HD-Wallet generation) the number of seed words depends on the parameter defined in KeyPairServiceConfiguration
      Specified by:
      generateHdWallet in interface KeyPairService
      Parameters:
      mnemonicSeedPassword - password or null which is used to seed the list of mnemonics
      Returns:
      keypair with private and public key as well as the generated list of mnemonic seed words wrapped into HdWallet
      Throws:
      AException - in case of an error

    • recoverHdWallet

      public HdWallet recoverHdWallet​(java.util.List<java.lang.String> mnemonicSeedWords, java.lang.String mnemonicSeedPassword) throws AException
      Description copied from interface: KeyPairService
      recover keypair from given mnemonic seed word list with given seed password
      Specified by:
      recoverHdWallet in interface KeyPairService
      Parameters:
      mnemonicSeedWords - the words to recover the Hdwallet
      mnemonicSeedPassword - the password that protects the keypair(s) generated with the seed phrase (can be null)
      Returns:
      instance of HdWallet
      Throws:
      AException - in case of an error

    • byteToHex

      public java.lang.String byteToHex​(byte[] key)
