Method Details

generateBip44Wallet

public static org.web3j.crypto.Bip39Wallet generateBip44Wallet(String password,
 File destinationDirectory)
                                                        throws org.web3j.crypto.exception.CipherException,
IOException

Generates a BIP-44 compatible Ethereum wallet on top of BIP-39 generated seed.

Parameters:

password - Will be used for both wallet encryption and passphrase for BIP-39 seed

destinationDirectory - The directory containing the wallet

Returns:

A BIP-39 compatible Ethereum wallet

Throws:

org.web3j.crypto.exception.CipherException - if the underlying cipher is not available

IOException - if the destination cannot be written to

generateBip44Wallet

public static org.web3j.crypto.Bip39Wallet generateBip44Wallet(String password,
 File destinationDirectory,
 boolean testNet)
                                                        throws org.web3j.crypto.exception.CipherException,
IOException

Generates a BIP-44 compatible Ethereum wallet on top of BIP-39 generated seed.

Parameters:

password - Will be used for both wallet encryption and passphrase for BIP-39 seed

destinationDirectory - The directory containing the wallet

testNet - should use the testNet derive path

Returns:

A BIP-39 compatible Ethereum wallet

Throws:

org.web3j.crypto.exception.CipherException - if the underlying cipher is not available

IOException - if the destination cannot be written to
